如果你按照上一章节的来的话,你现在的目录结构应该是这样的:
下面继续:
一、填充mybatis的配置文件
AccountMapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xupeng.mapper.AccountMapper">
<insert id="save" parameterType="account">
insert into account values (#{id},#{name},#{money})
</insert>
<select id="findAll" resultType="account">
select * from account
</select>
</mapper>
sqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--加载properties文件-->
<properties resource="jdbc.properties"></properties>
<!--定义别名-->
<typeAliases>
<!--<typeAlias type="com.xupeng.domain.Account" alias="account"></typeAlias>-->
<!--给这个包下所有实体设置别名。别名是首字母小写,或者首字母都行-->
<package name="com.xupeng.domain"/>
</typeAliases>
<!--环境-->
<environments default="development">
<environment id="development">
<transactionManager type="JDBC"></transactionManager>
<dataSource type="POOLED">
<property name="driver" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</dataSource>
</environment>
</environments>
<!--加载映射文件-->
<mappers>
<!--<mapper resource="com/xupeng/mapper/AccountMapper.xml"></mapper>-->
<package name="com.xupeng.mapper"/>
</mappers>
</configuration>
二、填充spring,springmvc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"
xmlns:aop="http://www.springframework.org/schema/aop"
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.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
<!--组件扫描,扫描service和mapper-->
<context:component-scan base-package="com.xupeng">
<!--排除controller,因为springmvc有扫了-->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:exclude-filter>
</context:component-scan>
</beans>
spring-mvc.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/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--组件扫描,扫描controller-->
<context:component-scan base-package="com.xupeng.controller"></context:component-scan>
<!--配置mvc注解驱动-->
<mvc:annotation-driven></mvc:annotation-driven>
<!--内部资源视图解析器-->
<bean id="resourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!--开放静态资源访问权限-->
<mvc:default-servlet-handler></mvc:default-servlet-handler>
</beans>
web.xml
<?xml version="1.0" encoding="utf-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<!--监听器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!--springmvc前端控制器-->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--乱码过滤器-->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
三、业务代码
AccountController
package com.xupeng.controller;
import com.xupeng.domain.Account;
import com.xupeng.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private AccountService accountService;
//保存
@RequestMapping("/save")
@ResponseBody
public String save(Account account){
accountService.save(account);
return "成功";
}
//查询
public ModelAndView findAll(){
List<Account> accountList = accountService.findAll();
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("accountList",accountList);
modelAndView.setViewName("accountList");
return modelAndView;
}
}
AccountServiceImpl
package com.xupeng.controller;
import com.xupeng.domain.Account;
import com.xupeng.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private AccountService accountService;
//保存
@RequestMapping(value = "/save",produces = "text/html;charset=utf-8")
@ResponseBody
public String save(Account account){
accountService.save(account);
return "成功";
}
//查询
@RequestMapping(value = "/findAll")
public ModelAndView findAll(){
List<Account> accountList = accountService.findAll();
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("accountList",accountList);
modelAndView.setViewName("accountList");
return modelAndView;
}
}
四、测试
