1、先看下项目结构
2、Spring mvc+Spring+mybatis框架搭建流程，首先在web.xml文件中配置Spring监听器及加载spring配置文件，其次配置spring mvc文件，并在web.xml中配置spring mvc的servlet,最后是配置mybatis文件下载
3、先看web.xml配置文件

<location>/WEB-INF/view/error/500.jsp</location>
</error-page>
</web-app>
4、我们在来看看spring mvc的配置文件mvc-config.xml
[html] view
plain copy
<?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:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd 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" default-autowire="byType">
<!-- 启动注解 -->
<mvc:annotation-driven />
<!-- 扫描注解包 -->
<context:component-scan base-package="com.demo"></context:component-scan>
<!-- 配置view页面 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 加载application.properties文件，这个文件一般都配置了数据库及数据库连接池等 -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer">
<property name="location">
<value>classpath:config/application.properties</value>
</property>
</bean>
<!-- 静态文件 -->
<mvc:resources mapping="/resources/**" location="/WEB-INF/resources/"></mvc:resources>
</beans>
5、常用配置信息如数据库连接池等信息，一般习惯配置在新的文件中application.properties
[plain] view
plain copy
#jdbc
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=root
jdbc.maxActive=50
c3p0.acquireIncrement=10
c3p0.minPoolSize=3
c3p0.maxPoolSize=200
c3p0.maxIdleTime=6000
6、spring基本配置，及spring 事物数据库连接池等配置
基本配置application-config.xml
[html] view
plain copy
<?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:p="http://www.springframework.org/schema/p"
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">
<!-- 扫描包 -->
<context:component-scan base-package="com.demo"/>
<!-- 开启注解 -->
<context:annotation-config></context:annotation-config>
<!-- 导入其他文件 -->
<import resource="data-source-tx.xml"></import>
</beans>
spring事物及数据库连接池等配置data-source-tx.xml
[html] view
plain copy
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 加载文件 -->
<context:property-placeholder location="classpath:config/application.properties"/>
<!-- 配置Mybatis的SqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:config/mybatis-config.xml" />
</bean>
<!-- 配置Mybatis映射dao层位置 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.demo.mapper"></property>
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
</bean>
<!-- dataSource -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"

</bean>
<!-- 事物 -->
<bean id="txManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 开启注解事物 -->

</beans>
7、Mybatis配置文件mybatis-config.xml
[html] view
plain copy
<?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>
<typeAliases>
<typeAlias alias="User" type="com.demo.model.User" />
<typeAlias alias="Kpi" type="com.demo.model.Kpi" />
<typeAlias alias="KpiDetail" type="com.demo.model.KpiDetail" />
</typeAliases>
</configuration>
配置文件讲完了，下面看看一个例子，用户登录下载
1、控制层controller
[java] view
plain copy
package com.demo.controller;
import java.util.HashMap;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.validation.Valid;
import com.demo.model.User;
import com.demo.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(value="/login",method=RequestMethod.GET,params="form")
public String toLogin(Model model){
User user = new User();
model.addAttribute(user);
return "user/login";
}
@RequestMapping(value="/login",method=RequestMethod.POST,produces="application/json")
@ResponseBody
public Map<String, Object> login(@Valid User user,BindingResult result){
Map<String,Object> map = new HashMap<String, Object>();
if(result.hasErrors()){
map.put("error", 1);
map.put("msg", "系统异常");
return map;
}
map = this.userService.login(user);
return map;
}
}
2、实体层model
[java] view
plain copy
package com.demo.model;
import java.io.Serializable;
public class User implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1482055695347272535L;
private long id;
private String username;
private String password;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
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;
}
}
3、业务层service
[java] view
plain copy
package com.demo.service;
import java.util.Map;
import com.demo.model.User;
public interface UserService {
public User findByUsername(String username);
public Map<String,Object> login(User user);
}
[java] view
plain copy
package com.demo.service.impl;
import java.util.HashMap;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.demo.mapper.UserMapper;
import com.demo.model.User;
import com.demo.service.UserService;
@Service
@Transactional
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
@Override
public User findByUsername(String username) {
return this.userMapper.findByUsername(username);
}
@Override
public Map<String, Object> login(User user) {
Map<String, Object> result = new HashMap<String, Object>();
User u = this.findByUsername(user.getUsername());
if(u == null){
result.put("error", 1);
result.put("msg", "用户名不存在");
return result;
}
if(user.getPassword().equals(u.getPassword())){
result.put("error", 0);
result.put("msg", "登录成功");
}else{
result.put("error", 1);
result.put("msg", "密码错误");
}
return result;
}
}
4、dao层
[java] view
plain copy
package com.demo.mapper;
import com.demo.model.User;
public interface UserMapper {
public User findByUsername(String username);
}
与UserMapper.java相对应的UserMapper.xml
[html] view
plain copy
<?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.demo.mapper.UserMapper">
<select id="findByUsername" parameterType="String" resultType="User">
select * from user where username = #{username}
</select>
</mapper>
5、sql脚本【下载地址】

6、需要用到的jar下载
2、Spring mvc+Spring+mybatis框架搭建流程，首先在web.xml文件中配置Spring监听器及加载spring配置文件，其次配置spring mvc文件，并在web.xml中配置spring mvc的servlet,最后是配置mybatis文件下载
3、先看web.xml配置文件
[html] view
plain copy

4、我们在来看看spring mvc的配置文件mvc-config.xml
[html] view
plain copy
<?xml version="1.0" encoding="UTF-8"?>

</bean>
<!-- 静态文件 -->
<mvc:resources mapping="/resources/**" location="/WEB-INF/resources/"></mvc:resources>
</beans>
5、常用配置信息如数据库连接池等信息，一般习惯配置在新的文件中application.properties
[plain] view
plain copy
#jdbc
jdbc.driverClassName=com.mysql.jdbc.Driver

c3p0.acquireIncrement=10
c3p0.minPoolSize=3
c3p0.maxPoolSize=200
c3p0.maxIdleTime=6000
6、spring基本配置，及spring 事物数据库连接池等配置
基本配置application-config.xml

7、Mybatis配置文件mybatis-config.xml
[html] view
plain copy
<?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>
<typeAliases>
<typeAlias alias="User" type="com.demo.model.User" />
<typeAlias alias="Kpi" type="com.demo.model.Kpi" />
<typeAlias alias="KpiDetail" type="com.demo.model.KpiDetail" />
</typeAliases>
</configuration>
配置文件讲完了，下面看看一个例子，用户登录下载
1、控制层controller
[java] view
plain copy
package com.demo.controller;
import java.util.HashMap;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.validation.Valid;
import com.demo.model.User;
import com.demo.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(value="/login",method=RequestMethod.GET,params="form")
public String toLogin(Model model){
User user = new User();
model.addAttribute(user);
return "user/login";
}
@RequestMapping(value="/login",method=RequestMethod.POST,produces="application/json")
@ResponseBody
public Map<String, Object> login(@Valid User user,BindingResult result){
Map<String,Object> map = new HashMap<String, Object>();
if(result.hasErrors()){
map.put("error", 1);
map.put("msg", "系统异常");
return map;
}
map = this.userService.login(user);
return map;
}
}
2、实体层model
[java] view
plain copy
package com.demo.model;
import java.io.Serializable;
public class User implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1482055695347272535L;
private long id;
private String username;
private String password;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
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;
}
}
3、业务层service
[java] view
plain copy
package com.demo.service;
import java.util.Map;
import com.demo.model.User;
public interface UserService {
public User findByUsername(String username);
public Map<String,Object> login(User user);
}
[java] view
plain copy
package com.demo.service.impl;
import java.util.HashMap;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.demo.mapper.UserMapper;
import com.demo.model.User;
import com.demo.service.UserService;
@Service
@Transactional
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
@Override
public User findByUsername(String username) {
return this.userMapper.findByUsername(username);
}
@Override
public Map<String, Object> login(User user) {
Map<String, Object> result = new HashMap<String, Object>();
User u = this.findByUsername(user.getUsername());
if(u == null){
result.put("error", 1);
result.put("msg", "用户名不存在");
return result;
}
if(user.getPassword().equals(u.getPassword())){
result.put("error", 0);
result.put("msg", "登录成功");
}else{
result.put("error", 1);
result.put("msg", "密码错误");
}
return result;
}
}
4、dao层
[java] view
plain copy
package com.demo.mapper;
import com.demo.model.User;
public interface UserMapper {
public User findByUsername(String username);
}
与UserMapper.java相对应的UserMapper.xml
[html] view
plain copy
<?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.demo.mapper.UserMapper">
<select id="findByUsername" parameterType="String" resultType="User">
select * from user where username = #{username}
</select>
</mapper>
