maven下整合SSM框架

工具:

一. 创建一个maven项目,下载所需要jar包

1.maven项目创建后目录,启动成功.

2.打开项目下的pom.xml 添加依赖jar包 (如果是第一次用maven下载,可能会有些慢,需要耐心等待)

二. 导入所有jar包之后,依次创建配置文件

1.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>
<display-name>Archetype Created Web Application</display-name>
<!-- 配置spring配置文件的位置和名称 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring_mybatis.xml</param-value>
</context-param>
<!-- 统一设置项目的字符编码  -->
<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>
<!-- 如果spring中bean的作用域使用request的话，需要配置如下节点 -->
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
<!-- 启动spring监听 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener </listener-class>
</listener>
<!-- 启动springMVC的前端控制器 -->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置springMVC配置文件的位置和名称 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring_mvc.xml</param-value>
</init-param>
<!-- 加载时启动前端控制器 -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
</web-app>

2.创建spring配置文件 spring_mybatis.xml(spring配置文件默认位置和名字是/WEB-INF/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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd"> <!-- 扫描模型层所在包路径 -->
<context:component-scan base-package="com.laolang.*.*.service.impl"></context:component-scan>

<!-- 声明数据源 -->
<!-- mySQL数据源Bean -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://localhost:3306/login?useUnicode=true&characterEncoding=utf-8</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>123456</value>
</property>
</bean>
<!-- 把数据源注入 给SqlSessionFactory 相当于Mybatis里的连库信息-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- mapper和resultmap配置路径       相当于声明SQL映射文件-->
<property name="mapperLocations">
<list>
<value>classpath:sqlMap/*Mapper.xml</value>
</list>
</property>
</bean>

<!--  设置扫描根路径也就是你的mybatis的mapper接口所在包路径；-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.laolang.*.*.mapper"/>
</bean>

<!-- TransactionManager 事务管理 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>

<!--启动spring事务注解功能-->
<tx:annotation-driven transaction-manager="transactionManager" />
</beans>

3.创建spring_mvc配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd"> 
<!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
<context:component-scan base-package="com.laolang.*.*.action" />
<!--避免IE执行AJAX时，返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 -->
</list>
</property>
</bean>
<!-- 定义跳转的文件的前后缀 ，视图解析配置-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>

</beans>

三. 配置文件创建完之后,我们依次创建一个控制器和页面,用来测试发送请求跳转页面

1.在欢迎页(index.jsp)中添加一个超链接用来发送请求

<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h2>Hello World!</h2>
<a href="<%=request.getContextPath()%>/sys/login.action">测试链接</a>
</body>
</html>

2.创建一个登陆页面(jsp/sys/login.jsp)

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h2>登陆页面</h2>
</body>
</html>

3.创建一个控制器LoginAction(com.laolang.system.login)

package com.laolang.system.login.action;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
*  描述: 登陆控制器
*  作者: 郎国峰
*  时间: 2018年1月18日 上午9:57:22
*/
@Controller
@RequestMapping("sys")
public class LoginAction {

/**
* @方法名: login
* @描述: 跳转登陆页
* @作者: 郎国峰
* @时间: 2018年1月18日 上午10:01:07
* @return
*/
@RequestMapping("login")
public String login(){
System.out.println("跳转登陆页面控制器");
return "jsp/sys/login";
}
}

四. 页面跳转没问题之后,我们进行对数据库查询的测试

1.创建数据库,并创建一张表,随便填条数据

2.创建数据库login中表sysuser对应的mapper接口,映射文件和实体类

package com.laolang.system.login.mapper;

import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.ResultMap;
import org.apache.ibatis.annotations.Select;

import com.laolang.system.login.entity.Sysuser;

public interface SysuserMapper {
int deleteByPrimaryKey(Integer id);

int insert(Sysuser record);

int insertSelective(Sysuser record);

Sysuser selectByPrimaryKey(Integer id);

int updateByPrimaryKeySelective(Sysuser record);

int updateByPrimaryKey(Sysuser record);

/**
* @方法名: queryUserByNameAndPassword
* @描述: 根据用户名和密码查询用户
* @作者: 郎国峰
* @时间: 2018年1月18日 上午11:35:14
* @param userName
* @param password
* @return
*/
@Select("select * from sysuser where username = #{userName} and password = #{password} ")
@ResultMap("BaseResultMap")
Sysuser queryUserByNameAndPassword(@Param("userName") String userName,@Param("password") String password);
}

<?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.laolang.system.login.mapper.SysuserMapper" >

</select>
<delete id="deleteByPrimaryKey" parameterType="java.lang.Integer" >
delete from sysuser
where id = #{id,jdbcType=INTEGER}
</delete>
<insert id="insert" parameterType="com.laolang.system.login.entity.Sysuser" >
insert into sysuser (id, username, password,
addtime, lasttime)
values (#{id,jdbcType=INTEGER}, #{username,jdbcType=VARCHAR}, #{password,jdbcType=VARCHAR},
#{addtime,jdbcType=VARCHAR}, #{lasttime,jdbcType=VARCHAR})
</insert>
<insert id="insertSelective" parameterType="com.laolang.system.login.entity.Sysuser" >
insert into sysuser
<trim prefix="(" suffix=")" suffixOverrides="," >
<if test="id != null" >
id,
</if>
<if test="username != null" >
username,
</if>
<if test="password != null" >
password,
</if>
<if test="addtime != null" >
addtime,
</if>
<if test="lasttime != null" >
lasttime,
</if>
</trim>
<trim prefix="values (" suffix=")" suffixOverrides="," >
<if test="id != null" >
#{id,jdbcType=INTEGER},
</if>
<if test="username != null" >
#{username,jdbcType=VARCHAR},
</if>
<if test="password != null" >
#{password,jdbcType=VARCHAR},
</if>
<if test="addtime != null" >
#{addtime,jdbcType=VARCHAR},
</if>
<if test="lasttime != null" >
#{lasttime,jdbcType=VARCHAR},
</if>
</trim>
</insert>
<update id="updateByPrimaryKeySelective" parameterType="com.laolang.system.login.entity.Sysuser" >
update sysuser
<set >
<if test="username != null" >
username = #{username,jdbcType=VARCHAR},
</if>
<if test="password != null" >
password = #{password,jdbcType=VARCHAR},
</if>
<if test="addtime != null" >
addtime = #{addtime,jdbcType=VARCHAR},

</set>
where id = #{id,jdbcType=INTEGER}
</update>
<update id="updateByPrimaryKey" parameterType="com.laolang.system.login.entity.Sysuser" >
update sysuser
set username = #{username,jdbcType=VARCHAR},
password = #{password,jdbcType=VARCHAR},
addtime = #{addtime,jdbcType=VARCHAR},
lasttime = #{lasttime,jdbcType=VARCHAR}
where id = #{id,jdbcType=INTEGER}
</update>
</mapper>

package com.laolang.system.login.entity;

public class Sysuser {
private Integer id;

private String username;

private String password;

private String addtime;

private String lasttime;

public Integer getId() {
return id;
}

public void setId(Integer id) {
this.id = id;
}

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username == null ? null : username.trim();
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password == null ? null : password.trim();
}

public String getAddtime() {
return addtime;
}

public void setAddtime(String addtime) {
this.addtime = addtime == null ? null : addtime.trim();
}

public String getLasttime() {
return lasttime;
}

public void setLasttime(String lasttime) {
this.lasttime = lasttime == null ? null : lasttime.trim();
}

@Override
public String toString() {
return "Sysuser [id=" + id + ", username=" + username + ", password="
+ password + ", addtime=" + addtime + ", lasttime=" + lasttime
+ "]";
}
}

五. 查询数据库

1.控制器添加查询模型

package com.laolang.system.login.action;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.laolang.system.login.entity.Sysuser;
import com.laolang.system.login.service.ILoginService;

/**
*  描述: 登陆控制器
*  作者: 郎国峰
*  时间: 2018年1月18日 上午9:57:22
*/
@Controller
@RequestMapping("sys")
public class LoginAction {
@Autowired
private ILoginService service;
/**
* @方法名: login
* @描述: 跳转登陆页
* @作者: 郎国峰
* @时间: 2018年1月18日 上午10:01:07
* @return
*/
@RequestMapping("login")
public String login(){
System.out.println("跳转登陆页面控制器");
Sysuser sysuser = service.queryUserByNameAndPassword("main", "123456");
System.out.println("根据用户名和密码进行查询数据库的结果"+sysuser);
return "jsp/sys/login";
}
}

2.创建模型层接口

package com.laolang.system.login.service;

import com.laolang.system.login.entity.Sysuser;

/**
* 标题: ILoginService.java
* 路径: com.laolang.system.login.service
* 描述: 登陆模块模型层接口
* 作者: 郎国峰
* 时间: 2018年1月18日 上午10:55:35
* 版本: @version V1.0
*/
public interface ILoginService {
/**
* @方法名: queryUserByNameAndPassword
* @描述: 根据用户名和密码查询用户
* @作者: 郎国峰
* @时间: 2018年1月18日 上午11:00:40
* @return
*/
public Sysuser queryUserByNameAndPassword(String userName,String password);
}

3.创建模型层实现类

package com.laolang.system.login.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.laolang.system.login.entity.Sysuser;
import com.laolang.system.login.mapper.SysuserMapper;
import com.laolang.system.login.service.ILoginService;
/**
* 标题: LoginServiceImpl.java
* 路径: com.laolang.system.login.service.impl
* 描述: 登陆模块模型层
* 作者: 郎国峰
* 时间: 2018年1月18日 上午11:02:25
* 版本: @version V1.0
*/
@Service
public class LoginServiceImpl implements ILoginService{
@Autowired
private SysuserMapper sysuserMapper;

public Sysuser queryUserByNameAndPassword(String userName, String password) {
Sysuser sysuser = sysuserMapper.queryUserByNameAndPassword(userName,password);
return sysuser;
}

}

六. 测试

启动项目,单击欢迎页测试链接,控制台打印跳转控制器及查询结果
