这是一个 spring 集成 mybatis 的小项目实践，通过 spring 的 bean 管理，配置 mybatis 的 mapper，同时使用阿里巴巴连接池 druid，连接到 postgresql 数据库，实现 insert 插入操作
- 首先使用 eclipse 创建一个 maven 项目（single maven project），编辑 pom

- 服务器启动首先加载 web.xml 配置文件，在这里我们设置一个 welcome file，指向 index.jsp，index.jsp 里面其实只是一个 form 表单，表单提交是有一个 servlet 控制，后台 servlet 使用 dopost 方法获取前台表单填充参数，并存储到数据库，下面是 web 配置文件。
<!-- 使用contextConfigLocation获取并初始化spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 服务器启动，初始化servlet，可以通过他获取spring上下文的bean，里面有个init()方法 -->
<servlet>
<servlet-name>ServerApplicationContext</servlet-name>
<servlet-class>com.spring.mybatis.servlet.ServerApplicationContext</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 这个是获取页面输入数据的servlet，并调用service层接口存储数据 -->
<servlet>
<servlet-name>ServletLogin</servlet-name>
<servlet-class>com.spring.mybatis.servlet.LoginServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<!-- 这里是阿里连接池druid的监控配置 -->
<filter>
<filter-name>DruidWebStatFilter</filter-name>
<filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
<init-param>
<param-name>exclusions</param-name>
<param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*,/rs/*</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>DruidWebStatFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>DruidStatView</servlet-name>
<servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>DruidStatView</servlet-name>
<url-pattern>/druid/*</url-pattern>
</servlet-mapping>
<!-- web初始化默认加载的页面 -->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
- 我们下面来看一下 spring 配置文件里面 bean 的配置，当我们配置 bean 的时候，应该注意他们的业务范围，以及应该怎样注入，这里使用的 setter 注入方式，从 web.xml 中可以看出 spring 配置文件是在 WEB-INF 下面的 applicationContext.xml，文件内容是：
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<bean id="loginService" class="com.spring.mybatis.service.impl.LoginServiceImpl">
<property name="loginDao" ref="loginDao"></property>
</bean>
<bean id="loginDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="com.spring.mybatis.dao.LoginDao"></property>
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mapperLocations" value="classpath*:com/spring/mybatis/mapper/*Mapper.xml"></property>
</bean>
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method = "close">
<property name="driverClassName" value="org.postgresql.Driver"></property>
<property name="url" value="jdbc:postgresql://localhost:5432/test_mybatis_db"></property>
<property name="username" value="postgres"></property>
<property name="password" value="dbms4Fna"></property>
<property name="maxActive" value="20"></property>
<property name="maxIdle" value="20"></property>
<property name="maxWait" value="6000"></property>
<property name="defaultAutoCommit" value="true"></property>
</bean>
</beans>
注入顺序大概是：
dataSource --->sqlSessionFactory --->loginDao --->loginService
- 我们的页面代码很简单，一个 form 表单
<form action="LoginServlet" method="post">
用户名:<br>
<input type="text" name="username"><br>
密 码:<br>
<input type="text" name="password"><br>
<input type="submit" value="提交">
</form>
- 下面是我们配置的一个 servlet 类，其中一个是为了在初始化时获得 ApplicationContext，即 ServerApplicationContext.java
package com.spring.mybatis.servlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
public class ServerApplicationContext extends HttpServlet {
private static final long serialVersionUID = 1L;
private static ApplicationContext serverContext = null;
@Override
public void init() throws ServletException {
super.init();
javax.servlet.ServletContext servletContext = getServletContext();
serverContext = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
System.out.println("================");
System.out.println("==serverContext begin==");
System.out.println("================");
}
public static ApplicationContext getApplicationContext() {
return serverContext;
}
}
- 这也是一个 servlet 类，类似于处理与前段页面交互的 Struts2 的 Action 类
package com.spring.mybatis.servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.spring.mybatis.domain.UserInfo;
import com.spring.mybatis.service.LoginService;
@WebServlet("/LoginServlet")
public class LoginServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public LoginServlet() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html;charset=gb2312");
request.setCharacterEncoding("gb2312");
String username = request.getParameter("username");
String password = request.getParameter("password");
LoginService loginService = (LoginService) ServerApplicationContext.getApplicationContext().getBean("loginService");
int age = 14;
char sex = '男';
int weight = 42;
UserInfo ui = new UserInfo();
ui.setUsername(username);
ui.setPassword(password);
ui.setAge(age);
ui.setSex(sex);
ui.setWeight(weight);
loginService.insertUserInfo(ui);
/*try {
Class.forName("org.postgresql.Driver");
} catch (Exception e) {
System.out.print("Class Not Found Exception");
}
String url = "jdbc:postgresql://localhost:5432/test_mybatis_db";
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
try {
conn = (Connection) DriverManager.getConnection(url,"postgres","dbms4Fna");
stmt = (Statement) conn.createStatement();
String sql = "insert into userinfo (username,userpsw,age,sex,weight) values ('"+username+"','"+psw+"',25,'男',52)";
PreparedStatement ps = conn.prepareStatement(sql);
int result=ps.executeUpdate();
if( result>0 ){
System.out.println("Insert OK");
}
} catch (Exception e) {
e.printStackTrace();
}*/
}
}
- 上面的 LoginServlet 里调用了 service 层接口
package com.spring.mybatis.service;
import com.spring.mybatis.domain.UserInfo;
public interface LoginService {
public void insertUserInfo(UserInfo userInfo);
}
- 接下来是 service 层接口的实现类，调用 dao
package com.spring.mybatis.service.impl;
import com.spring.mybatis.dao.LoginDao;
import com.spring.mybatis.domain.UserInfo;
import com.spring.mybatis.service.LoginService;
public class LoginServiceImpl implements LoginService {
private LoginDao loginDao ;
public void setLoginDao(LoginDao loginDao) {
this.loginDao = loginDao;
}
@Override
public void insertUserInfo(UserInfo userInfo) {
loginDao.insertUserInfo(userInfo);
}
}
- 在我们的 dao 层只需要定义一个接口即可
package com.spring.mybatis.dao;
import com.spring.mybatis.domain.UserInfo;
public interface LoginDao {
public void insertUserInfo(UserInfo userInfo);
}
- 下面是 mybatis 重要的类，首先我们定义 pojo（domain），可以根据此 pojo 自动生成 sql 代码，连接并操作数据库
package com.spring.mybatis.domain;
public class UserInfo {
private String username;
private String password;
private int age;
private char sex;
private int weight;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public int getWeight() {
return weight;
}
public void setWeight(int weight) {
this.weight = weight;
}
public char getSex() {
return sex;
}
public void setSex(char sex) {
this.sex = sex;
}
@Override
public String toString() {
return "UserInfo [username=" + username + ", password=" + password + ", age=" + age + ", sex=" + sex
+ ", weight=" + weight + "]";
}
}
- 创建 mapper 包，存放 mapper.xml 文件
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<!-- 注意这里的命名空间要指向dao，类型指向domain对应实体类 -->
<mapper namespace="com.spring.mybatis.dao.LoginDao" >
<resultMap id="BaseResultMap" type="com.spring.mybatis.domain.UserInfo" >
<id column="username" property="username" jdbcType="VARCHAR" />
<result column="userpsw" property="password" jdbcType="VARCHAR" />
<result column="age" property="age" jdbcType="INTEGER" />
<result column="sex" property="sex" jdbcType="CHAR" />
<result column="weight" property="weight" jdbcType="INTEGER" />
</resultMap>
<!-- 这里的id要和dao接口的方法名对应 -->
<insert id="insertUserInfo" parameterType="com.spring.mybatis.domain.UserInfo" >
insert into public.userinfo (username, userpsw, age,
sex, weight)
values (#{username,jdbcType=VARCHAR}, #{password,jdbcType=VARCHAR}, #{age,jdbcType=INTEGER},
#{sex,jdbcType=CHAR}, #{weight,jdbcType=INTEGER})
</insert>
</mapper>
