2、springBoot + hibernate + Druid + MySQL + servlet(jsp)
不废话,直接上代码
一、maven的pom文件
<?xml version="1.0" encoding="UTF-8"?>4.0.0 com.zsx demo war 0.0.1 zsx Maven Webapp http://maven.apache.org UTF-8 1.7 7.0.69 org.springframework.boot spring-boot-starter-parent 1.4.0.RELEASE org.apache.tomcat.embed tomcat-embed-jasper javax.servlet jstl org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-data-jpa mysql mysql-connector-java org.springframework.boot spring-boot-starter-tomcat provided org.springframework.boot spring-boot-devtools com.alibaba fastjson 1.2.16 com.alibaba druid 1.0.25 org.apache.poi poi 3.14 org.springframework.boot spring-boot-starter-test test io.springfox springfox-swagger2 2.6.0 io.springfox springfox-swagger-ui 2.6.0 / org.springframework.boot spring-boot-maven-plugin org.springframework springloaded 1.2.6.RELEASE ali ali Repository http://maven.aliyun.com/nexus/content/groups/public/ false 
二、项目架构
想想还是介绍一下项目的目录结构,这样方便梳理整体的架构配置

        UtilTest.java
标准的maven项目结构,其中Java下是dao、service、controller ,还有实体类映射entity,其他配置config
三、resources下的应用配置文件application.properties
#server.port=9090 # 数据库访问配置 # 主数据源,默认的 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.url=jdbc:mysql://localhost:3306/test spring.datasource.username= root spring.datasource.password= root spring.datasource.driverClassName = com.mysql.jdbc.Driver # 下面为连接池的补充设置,应用到上面所有数据源中 # 初始化大小,最小,最大 spring.datasource.initialSize=5 spring.datasource.minIdle=5 spring.datasource.maxActive=20 # 配置获取连接等待超时的时间 spring.datasource.maxWait=60000 # 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 spring.datasource.timeBetweenEvictionRunsMillis=60000 # 配置一个连接在池中最小生存的时间,单位是毫秒 spring.datasource.minEvictableIdleTimeMillis=300000 spring.datasource.validationQuery=SELECT 1 FROM DUAL spring.datasource.testWhileIdle=true spring.datasource.testOnBorrow=false spring.datasource.testOnReturn=false # 打开PSCache,并且指定每个连接上PSCache的大小 spring.datasource.poolPreparedStatements=true spring.datasource.maxPoolPreparedStatementPerConnectionSize=20 # 配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙 spring.datasource.filters=stat,wall,log4j # 通过connectProperties属性来打开mergeSql功能;慢SQL记录 spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 # 合并多个DruidDataSource的监控数据 spring.datasource.useGlobalDataSourceStat=true #JPA Configuration: spring.jpa.database=MYSQL # Show or not log for each sql query spring.jpa.show-sql=false spring.jpa.generate-ddl=true # Hibernate ddl auto (create, create-drop, update) spring.jpa.hibernate.ddl-auto=create #spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.ImprovedNamingStrategy #spring.jpa.database=org.hibernate.dialect.MySQL5InnoDBDialect spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect spring.mvc.view.prefix=/WEB-INF/view/ spring.mvc.view.suffix=.jsp #spring.resources.static-locations=classpath:/resources/,classpath:/static/
四、启动应用主类文件 Application.java
package com.zsx;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
@SpringBootApplication
@ServletComponentScan // 扫描使用注解方式的servlet
public class Application {
  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }
}
若需要部署到外部的tomcat容器中,则添加下面类即可。
package com.zsx;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
/**
 * 修改启动类,继承 SpringBootServletInitializer 并重写 configure 方法
 * @author ZSX
 *
 */
public class SpringBootStartApplication extends SpringBootServletInitializer {
  private static final Logger logger = LoggerFactory.getLogger(SpringBootStartApplication.class);
  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    return builder.sources(Application.class);
  }
}
五、数据库连接池Druid的配置
  package com.zsx.common.config;
  import java.sql.SQLException;
  import javax.sql.DataSource;
  import org.springframework.beans.factory.annotation.Value;
  import org.springframework.context.annotation.Bean;
  import org.springframework.context.annotation.Configuration;
  import org.springframework.context.annotation.Primary;
  import com.alibaba.druid.pool.DruidDataSource;
  /**
   * DruidDBConfig类被@Configuration标注,用作配置信息; 
   * DataSource对象被@Bean声明,为Spring容器所管理, 
   * @Primary表示这里定义的DataSource将覆盖其他来源的DataSource。
   * @author ZSX
   *jdbc.url=${jdbc.url} 
   *最新的支持方式如下: 
   *jdbc.url=@jdbc.url@ 
   */
  @Configuration
  public class DruidDBConfig {
  // private Logger logger = LoggerFactory.getLogger(DruidDBConfig.class);
    @Value("${spring.datasource.url}")
    private String dbUrl;
    @Value("${spring.datasource.username}")
    private String username;
    @Value("${spring.datasource.password}")
    private String password;
    @Value("${spring.datasource.driverClassName}")
    private String driverClassName;
    @Value("${spring.datasource.initialSize}")
    private int initialSize;
    @Value("${spring.datasource.minIdle}")
    private int minIdle;
    @Value("${spring.datasource.maxActive}")
    private int maxActive;
    @Value("${spring.datasource.maxWait}")
    private int maxWait;
    @Value("${spring.datasource.timeBetweenEvictionRunsMillis}")
    private int timeBetweenEvictionRunsMillis;
    @Value("${spring.datasource.minEvictableIdleTimeMillis}")
    private int minEvictableIdleTimeMillis;
    @Value("${spring.datasource.validationQuery}")
    private String validationQuery;
    @Value("${spring.datasource.testWhileIdle}")
    private boolean testWhileIdle;
    @Value("${spring.datasource.testOnBorrow}")
    private boolean testOnBorrow;
    @Value("${spring.datasource.testOnReturn}")
    private boolean testOnReturn;
    @Value("${spring.datasource.poolPreparedStatements}")
    private boolean poolPreparedStatements;
    @Value("${spring.datasource.maxPoolPreparedStatementPerConnectionSize}")
    private int maxPoolPreparedStatementPerConnectionSize;
    @Value("${spring.datasource.filters}")
    private String filters;
    @Value("{spring.datasource.connectionProperties}")
    private String connectionProperties;
    @Bean // 声明其为Bean实例
    @Primary // 在同样的DataSource中,首先使用被标注的DataSource
    public DataSource dataSource() {
      DruidDataSource datasource = new DruidDataSource();
      datasource.setUrl(this.dbUrl);
      datasource.setUsername(username);
      datasource.setPassword(password);
      datasource.setDriverClassName(driverClassName);
      // configuration
      datasource.setInitialSize(initialSize);
      datasource.setMinIdle(minIdle);
      datasource.setMaxActive(maxActive);
      datasource.setMaxWait(maxWait);
      datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
      datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
      datasource.setValidationQuery(validationQuery);
      datasource.setTestWhileIdle(testWhileIdle);
      datasource.setTestOnBorrow(testOnBorrow);
      datasource.setTestOnReturn(testOnReturn);
      datasource.setPoolPreparedStatements(poolPreparedStatements);
      datasource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);
      try {
        datasource.setFilters(filters);
      } catch (SQLException e) {
      }
      datasource.setConnectionProperties(connectionProperties);
      return datasource;
    }
  }
springboot里默认使用tomcat的上传文件大小限制,即1MB, 修改用下面的配置类:
import javax.servlet.MultipartConfigElement;
import org.springframework.boot.web.servlet.MultipartConfigFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MultipartConfig {
  @Bean
  public MultipartConfigElement multipartConfigElement(){
    MultipartConfigFactory factory = new MultipartConfigFactory();
    factory.setMaxFileSize("10MB");
    factory.setMaxRequestSize("10MB");
    return factory.createMultipartConfig();
  }
}
六、开启Druid的数据库监控配置
1、配置Filter
import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;
import com.alibaba.druid.support.http.WebStatFilter;
/**
 * 配置druid监控统计功能
 * 配置Filter
 * @author ZSX
 *
 */
@WebFilter(filterName = "druidWebStatFilter", urlPatterns = "/*",
  initParams = {
      @WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略资源
  }
)
public class DruidStatFilter extends WebStatFilter {
}
2、 配置web访问的servlet
import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;
import com.alibaba.druid.support.http.StatViewServlet;
/**
 * 配置druid监控统计功能
 * 在SpringBoot项目中基于注解的配置,如果是web.xml配置,按规则配置即可
 * @author ZSX
 *
 */
@WebServlet(urlPatterns = "/druid/*",
  initParams = {
//     @WebInitParam(name = "allow", value = "192.168.16.110,127.0.0.1"), // IP白名单 (没有配置或者为空,则允许所有访问)
//     @WebInitParam(name="deny",value="192.168.16.111"), // IP黑名单 (存在共同时,deny优先于allow)
      @WebInitParam(name="loginUsername",value="druid"),// 用户名
      @WebInitParam(name="loginPassword",value="druid"),// 密码
      @WebInitParam(name="resetEnable",value="false")// 禁用HTML页面上的“Reset All”功能
  }
)
public class DruidStatViewServlet extends StatViewServlet {
}
这样启动项目后在浏览器中输入地址:端口/druid,就可以看到druid的监控web页面了
七、 拦截器配置
  import org.springframework.context.annotation.Configuration;
  import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
  import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
  import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
  @Configuration
  public class WebAppConfigurer extends WebMvcConfigurerAdapter {
    /**
     * 配置拦截器
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
      // TODO Auto-generated method stub
      // 多个拦截器组成一个拦截器链
      // addPathPatterns 用于添加拦截规则
      // excludePathPatterns 用户排除拦截
      registry.addInterceptor(new AuthInterceptor()).addPathPatterns("/**");
      super.addInterceptors(registry);
    }
    /**
     * 添加自定义的静态资源映射
     这里使用代码的方式自定义目录映射,并不影响Spring Boot的默认映射,可以同时使用。
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
  //   registry.addResourceHandler("/new/**").addResourceLocations("classpath:/new/");
  //   registry.addResourceHandler("/**").addResourceLocations("/");
      super.addResourceHandlers(registry);
    }
  }
八、swagger发布api测试配置(可忽略)
  import org.springframework.context.annotation.Bean;
  import org.springframework.context.annotation.Configuration;
  import springfox.documentation.builders.ApiInfoBuilder;
  import springfox.documentation.builders.PathSelectors;
  import springfox.documentation.builders.RequestHandlerSelectors;
  import springfox.documentation.service.ApiInfo;
  import springfox.documentation.spi.DocumentationType;
  import springfox.documentation.spring.web.plugins.Docket;
  import springfox.documentation.swagger2.annotations.EnableSwagger2;
  @Configuration
  @EnableSwagger2
  public class Swagger2 {
    @Bean
    public Docket createRestApi(){
      return new Docket(DocumentationType.SWAGGER_2)
          .apiInfo(apiInfo())
          .select()
          .apis(RequestHandlerSelectors.basePackage("com.zsx.controller.api"))
          .paths(PathSelectors.any())
          .build();
    }
    private ApiInfo apiInfo(){
      return new ApiInfoBuilder()
          .title("Spring Boot中使用Swagger2构建RESTful APIs")
          .description("描述")
          .termsOfServiceUrl("http://zsx.com.cn")
          .version("1.0")
          .build();
    }
  }
至此,所有的配置已完成,下面是一个操作数据的简单demo
九、实体类
  @Entity
  @Table(name = "t_user")
  public class Tuser implements java.io.Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long id;
    @Column(name = "username")
    private String userName;
    @Column(name = "password")
    private String passWord;
    @Column(name = "email")
    private String email;
    @Column(name = "mobile")
    private String mobile;
    @Column(name = "nickname")
    private String nickName;
    // 省略getter 和 setter
  }
十、dao层
1、使用jpa基本可以实现不写sql,(但实际开发中,业务逻辑会很复杂,一点不写sql完全不现实)
2、注意添加@Repository注解, 添加JpaSpecificationExecutor继承可以方便分页
3、 看些jpa的查询语法资料
import java.util.List; import java.util.Map; import org.springframework.data.domain.Pageable; import org.springframework.data.jpa.repository.JpaSpecificationExecutor; import org.springframework.data.jpa.repository.Query; import org.springframework.data.repository.PagingAndSortingRepository; import org.springframework.data.repository.query.Param; import org.springframework.stereotype.Repository; @Repository public interface TuserDao extends PagingAndSortingRepository, JpaSpecificationExecutor { Tuser findByUserName(String userName); @Query("from Tuser t where id = :id") List queryFamilyList(@Param("id") Long id, Pageable pageable); } 
十一、service和controller没啥好说的,跟原先的一样,下面再提供一个单元测试的demo
  import java.util.List;
  import javax.persistence.EntityManager;
  import org.junit.Test;
  import org.junit.runner.RunWith;
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.boot.test.SpringApplicationConfiguration;
  import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
  import org.springframework.test.context.web.WebAppConfiguration;
  import com.alibaba.fastjson.JSON;
  import com.golden.Application;
  import com.golden.dao.TUserDao;
  import com.golden.entity.Tuser;
  import com.golden.util.GeneratePageable;
  @RunWith(SpringJUnit4ClassRunner.class)
  //指定我们SpringBoot工程的Application启动类
  @SpringApplicationConfiguration(classes = Application.class)
  //由于是Web项目,Junit需要模拟ServletContext,因此我们需要给我们的测试类加上@WebAppConfiguration
  @WebAppConfiguration
  public class UtilTest {
    @Autowired
    private TUserDao dao;
    @Autowired
    private EntityManager em;
    @Test
    public void test1(){
      dao.findByUserName("admin");
    }
    @Test
    public void test2(){
      // 使用jpa提供的分页类
      java.util.List list = new ArrayList();
      Order order = new Order(Direction.DESC, "createTime");
      list.add(order);
      Sort sort = new Sort(list);
      Pageable pageable = new PageRequest(0, 10, sort);
      Page findAll = dao.findAll(pageable);
    }
    @Test
    public void test3(){
      EntityManager em = dao.getEntityManager();
      Query query = em.createNativeQuery("select * from t_user limit 1");
      Object singleResult = query.getSingleResult();
      System.out.println(singleResult);
    }
    /*
  //执行原生SQL
  Query nativeQuery = em.createNativeQuery(String sql);
  //指定返回对象类型
  nativeQuery.unwrap(SQLQuery.class).setResultTransformer(Transformers.aliasToBean( Class resultType));
  //返回对象
  List resultList = nativeQuery.getResultList(); 
     */
  }
    后记:
不用Druid的可以把有关Druid的配置全部删掉,swagger的同理
这里没有使用hibernate.cfg.xml配置文件,主要习惯了在实体类里配置字段了,不怎么用hibernate的映xml文件了,但其实配置起来跟springmvc项目一样
说实话这里使用jpa操作数据库,没感觉有多方便,因为总有各种奇葩的需求,当然也可能是我没深入研究,所以建议改用Mybatis,这个我会再写一篇springboot加mybatis的配置教程的,最后,还可以使用原生的sql查询,即使用单元测试里的EntityManager对象去执行sql,返回结果可以指定对象类型,也很方便
还需要注意的一个点是静态文件的存放位置,这个跟原先的项目不一样,原先是在webapp下,但springboot是默认放在resources下的static目录下的,还有其他默认目录和配置,自行搜索
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持创新互联。
