前一段写了前2天的内容,本来想一个框架一个框架网上增.后来发现不好整... 这次参考网上的文章,一次将3个框架整合到一起.记录下来.

大体步骤:

1.新建maven web 项目

2.引入jar包

3.写业务代码

4.配置文件

5.测试

开始:

一:

1)第一步直接上图,new maven project

2. 这里选择 maven-archetype-webapp, 但是这个出来默认的是web module是2.3,jdk是1.5,貌似要使用自定义catalog才可以自己设置.

3.这个基本都是随便写了. artifactid 是项目名称

4. finish后,生成目录结构如下图,可以看到没有src的路径,

5.修改 jre lib位置,不使用默认的

7. 修改后,再看目录, 已经有src目录了, 可能是个bug导致的.

8.到project facets, 修改jdk版本和 web module,发现报错 cannot change version of project facet dynamic web module to 3.0

9.打开navigator视图,到settings文件夹下,将里面的配置文件中的JDK版本 1.5,改到1.7, web module 2.3 改到 3.0

10. 还要修改下web.xml 修改后如下

<?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" 
         xmlns:web="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_3_0.xsd" version="3.0">
</web-app>

第一步完成,开始第二部.

二:引入jar包

这个就比较简单,需要的jar包,引入到pom.xml就可以了,直接贴上代码

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

三:配置文件

1.main-content.xml , 相当与 application-content.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"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans.xsd">
  
  <import resource="spring-mybatis.xml" />
</beans>

2.spring-mybatis.xml, 用于配置数据源

<?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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans  
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd  
                        http://www.springframework.org/schema/context  
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd">
	<!-- 自动扫描 -->
	<context:component-scan base-package="com.xm.common" />
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />

	</bean>

	<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!-- 自动扫描mapping.xml文件 -->
		<property name="mapperLocations" value="classpath:com/xm/common/mapping/*.xml"></property>
	</bean>

	<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.xm.common.dao" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	</bean>

	</bean>

</beans>

3.spring-mvc.xml , 用于配置 springmvc

       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"
	default-lazy-init="true">

	<!-- DispatcherServlet Context: defines this servlet's request-processing 
		infrastructure -->

	<!-- Enables the Spring MVC @Controller programming model -->
	<mvc:annotation-driven />
	<context:component-scan base-package="com.xm.common.controller" />


	<!-- Resolves views selected for rendering by @Controllers to .jsp resources 
		in the /WEB-INF/views directory -->
	<beans:bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<beans:property name="prefix" value="/WEB-INF/jsp/" />
		<beans:property name="suffix" value=".jsp" />
	</beans:bean>
	
	<!-- file upload -->  
<!-- 	<beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />   -->
</beans:beans>

4.web.xml ,配置 springmvc及一些其他的

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee"

	</servlet>
	<servlet-mapping>
		<servlet-name>SpringMVC</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>

四:代码

model

package com.xm.common.model;

import java.io.Serializable;

public class User implements Serializable {

	private static final long serialVersionUID = 1L;
	
	private Integer id;
	private String userName;
	private String password;
	private Integer age;
	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;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	
	@Override
	public String toString() {
		return "User [id=" + id + ", userName=" + userName + ", password="
				+ password + ", age=" + age + "]";
	}
    
	
}

dao

package com.xm.common.dao;

import com.xm.common.model.User;

public interface UserDao {
    User selectByPrimaryKey(Integer id);
}

mapping

<?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.xm.common.dao.UserDao">
	<resultMap id="BaseResultMap" type="com.xm.common.model.User">
		<id column="id" property="id" jdbcType="INTEGER" />
		<result column="user_name" property="userName" jdbcType="VARCHAR" />
		<result column="password" property="password" jdbcType="VARCHAR" />
		<result column="age" property="age" jdbcType="INTEGER" />
	</resultMap>

	<sql id="Base_Column_List">
		id, user_name, password, age
	</sql>
	<select id="selectByPrimaryKey" resultMap="BaseResultMap"
		parameterType="java.lang.Integer">
		select
		<include refid="Base_Column_List" />
		from user_t
		where id = #{id,jdbcType=INTEGER}
	</select>
</mapper>

service

package com.xm.common.service;

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

import com.xm.common.dao.UserDao;
import com.xm.common.model.User;


@Service("userService")
public class UserService {
	@Autowired
    private UserDao userDao;  
	
    public User getUserById(int userId) {  
        return this.userDao.selectByPrimaryKey(userId);  
    } 
}

controller

package com.xm.common.controller;

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

import com.xm.common.model.User;
import com.xm.common.service.UserService;

@Controller
@RequestMapping("/user")
public class UserController {
	@Autowired
	private UserService userService;
	
	@RequestMapping("/showUser")
	public String toIndex(Model model,Integer userId){
		User user = this.userService.getUserById(userId);
		model.addAttribute("user", user);
		return "showUser";
	}
}

showUser.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
	<title>测试</title>
  </head>
  
  <body>
    ${user.userName}
  </body>
</html>

五:部署项目,在浏览器访问 ,要记得在数据库加这个表
