利用Intellij+MAVEN搭建SpringJDBC+MySql+SpringMVC项目详解

1 配置MAVEN的配置文件pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>SpringJDBCTest1</groupId>  <artifactId>SpringJDBCTest1</artifactId>  <packaging>war</packaging>  <version>1.0-SNAPSHOT</version>  <name>SpringJDBCTest1 Maven Webapp</name>  <url>http://maven.apache.org</url>  <dependencies>    <!--spring-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-beans</artifactId>      <version>4.3.1.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>4.3.1.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>4.3.1.RELEASE</version>    </dependency>    <!--Spring Web + Spring MVC-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-web</artifactId>      <version>4.3.1.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>4.3.1.RELEASE</version>    </dependency>    <!--NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config-->    <!-- https://mvnrepository.com/artifact/javax.servlet/jstl -->    <dependency>      <groupId>javax.servlet</groupId>      <artifactId>jstl</artifactId>      <version>1.2</version>    </dependency>    <dependency>      <groupId>taglibs</groupId>      <artifactId>standard</artifactId>      <version>1.1.2</version>    </dependency>    <!--servlet/jsp api start-->    <dependency>      <groupId>javax.servlet</groupId>      <artifactId>servlet-api</artifactId>      <version>2.5</version>    </dependency>    <!-- https://mvnrepository.com/artifact/javax.servlet.jsp/jsp-api -->    <dependency>      <groupId>javax.servlet.jsp</groupId>      <artifactId>jsp-api</artifactId>      <version>2.2</version>    </dependency>    <!--mysql driver-->    <dependency>      <groupId>mysql</groupId>      <artifactId>mysql-connector-java</artifactId>      <version>5.1.6</version>    </dependency>    <!--jdbc-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>3.0.5.RELEASE</version>    </dependency>    <!--c3p0-->    <dependency>      <groupId>com.mchange</groupId>      <artifactId>c3p0</artifactId>      <version>0.9.5.1</version>    </dependency>    <!--aspectj-->    <dependency>      <groupId>org.aspectj</groupId>      <artifactId>aspectjweaver</artifactId>      <version>1.8.6</version>    </dependency>    <dependency>      <groupId>org.aspectj</groupId>      <artifactId>aspectjrt</artifactId>      <version>1.8.6</version>    </dependency>    <!--mybatis-->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis</artifactId>      <version>3.3.0</version>    </dependency>    <!--mybatis spring整合-->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis-spring</artifactId>      <version>1.2.3</version>    </dependency>  </dependencies>  <build>    <finalName>SpringJDBCTest1</finalName>    <plugins>      <!--servlet容器 jetty插件-->      <plugin>        <groupId>org.eclipse.jetty</groupId>        <artifactId>jetty-maven-plugin</artifactId>        <version>9.3.10.v20160621</version>      </plugin>      <!--mybatis 逆向工程插件-->      <plugin>        <groupId>org.mybatis.generator</groupId>        <artifactId>mybatis-generator-maven-plugin</artifactId>        <version>1.3.2</version>        <configuration>          <verbose>true</verbose>          <overwrite>true</overwrite>        </configuration>      </plugin>      <plugin>        <groupId>org.apache.maven.plugins</groupId>        <artifactId>maven-compiler-plugin</artifactId>        <configuration>          <source>1.7</source>          <target>1.7</target>        </configuration>      </plugin>    </plugins>  </build></project>

2 src下建java包和类：

实体类：Employee.java

package com.springjdbc.entities;/** * Created by wanggenshen_sx on 2016/12/23. */public class Employee {   private int id;   private String lastName;   private String email;   public int getId() {      return id;   }   public void setId(int id) {      this.id = id;   }   public String getLastName() {      return lastName;   }   public void setLastName(String lastName) {      this.lastName = lastName;   }   public String getEmail() {      return email;   }   public void setEmail(String email) {      this.email = email;   }   @Override   public String toString() {      return "Employee [id=" + id + ", lastName=" + lastName + ", email="            + email+" ]" ;   }}

持久层类：EmployeeDao.java

这里注入JdbcTemplate,使用SpringJDBC框架。

package com.springjdbc.dao;import com.springjdbc.entities.Employee;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.jdbc.core.BeanPropertyRowMapper;import org.springframework.jdbc.core.JdbcTemplate;import org.springframework.jdbc.core.RowMapper;import org.springframework.stereotype.Repository;/** * Created by wanggenshen_sx on 2016/12/23. */@Repositorypublic class EmployeeDao {   @Autowired   private JdbcTemplate jdbcTemplate;   public Employee get(int id){      String sql="SELECT id, lastName,email FROM employee WHERE id=?";      RowMapper<Employee> rowMapper=new BeanPropertyRowMapper<>(Employee.class);      Employee employee=jdbcTemplate.queryForObject(sql, rowMapper,id);      return employee;   }}

控制器：EmployeeController.java

package com.springjdbc.controller;import com.springjdbc.dao.EmployeeDao;import com.springjdbc.entities.Employee;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.jdbc.core.BeanPropertyRowMapper;import org.springframework.jdbc.core.JdbcTemplate;import org.springframework.jdbc.core.RowMapper;import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import java.util.List;import java.util.Map;/** * Created by wanggenshen_sx on 2016/12/23. */@Controllerpublic class EmployeeController {   private ApplicationContext ctx=null;   private JdbcTemplate jdbcTemplate=null;   private EmployeeDao employeeDao ;   private NamedParameterJdbcTemplate namedParameterJdbcTemplate=null;   {      ctx=new ClassPathXmlApplicationContext("applicationContext.xml");      jdbcTemplate =(JdbcTemplate) ctx.getBean("jdbcTemplate");      employeeDao = ctx.getBean(EmployeeDao.class);      namedParameterJdbcTemplate=(NamedParameterJdbcTemplate) ctx.getBean("namedParameterJdbcTemplate");   }   @RequestMapping(value = "/listAllEmployee",method = RequestMethod.GET)   public String list(Map<String,Object> map){      String sql="SELECT id, lastName,email FROM employee";      RowMapper<Employee> rowMapper=new BeanPropertyRowMapper<>(Employee.class);      List<Employee> employees=jdbcTemplate.query(sql, rowMapper);      map.put("employees",employees);      return "list";   }}

3  配置sping和spingmvc的配置文件：

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:tx="http://www.springframework.org/schema/tx"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">    <context:component-scan base-package="com.springjdbc.dao"></context:component-scan>    <!-- 导入资源文件 -->    <context:property-placeholder location="classpath:db.properties"/>    <!-- 配置C3P0数据源 -->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">        <property name="user" value="${jdbc.user}"></property>        <property name="password" value="${jdbc.password}"></property>        <property name="driverClass" value="${jdbc.driverClass}"></property>        <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>        <property name="initialPoolSize" value="${jdbc.initPoolSize}"></property>        <property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property>    </bean>    <!-- 配置spring-jdbcTemplate模板 -->    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">        <property name="dataSource" ref="dataSource"></property>    </bean>    <!-- 配置 NamedParameterJdbcTemplate,         该对象可以使用具名参数, 其没有无参数的构造器, 所以必须为其构造器指定参数 -->    <bean id="namedParameterJdbcTemplate" class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">        <constructor-arg ref="dataSource"></constructor-arg>    </bean>    <!-- 配置事务管理器 -->    <bean id="transactionManager"          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource"></property>    </bean>    <!-- 启用事务注解 -->    <tx:annotation-driven transaction-manager="transactionManager"/>    <!-- spring注解模式配置 -->    <context:annotation-config/></beans>

springmvc-servlet.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:context="http://www.springframework.org/schema/context"       xmlns:mvc="http://www.springframework.org/schema/mvc"       xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.1.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.1.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">    <mvc:annotation-driven />    <mvc:default-servlet-handler/>    <!-- 启动包扫描功能 -->    <context:component-scan base-package="com.springjdbc.controller" />    <!-- 对模型视图名称的解析，在请求时模型视图名称添加前后缀 -->    <bean id="viewResolverCommon" class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/WEB-INF/views/"/>        <property name="suffix" value=".jsp"/>        <property name="viewClass"  value="org.springframework.web.servlet.view.JstlView" />    </bean></beans>

4 配置web.xml

<!DOCTYPE web-app PUBLIC        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"        "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app xmlns="http://java.sun.com/xml/ns/javaee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"         version="3.0">  <!--配置springmvc DispatcherServlet-->  <servlet>    <servlet-name>springmvc-servlet</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:springmvc-servlet.xml</param-value>    </init-param>    <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>springmvc-servlet</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:applicationContext.xml</param-value>  </context-param>  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener></web-app>

5 建显示页面list.jsp

<%--  Created by IntelliJ IDEA.  User: wanggenshen_sx  Date: 2016/12/23  Time: 16:56  To change this template use File | Settings | File Templates.--%><%@ page contentType="text/html;charset=UTF-8" language="java" %><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %><html><head>    <title>Show Page</title></head><body>    <table border="1" cellspacing="0" cellpadding="10">        <tr>            <th>ID</th>            <th>LastName</th>            <th>Email</th>        </tr>        <c:forEach items="${employees}" var="emp">            <tr>                <th>${emp.id}</th>                <th>${emp.lastName}</th>                <th>${emp.email}</th>            </tr>        </c:forEach>    </table></body></html>
