SSM系列1：簡易詳細的（Spring +Springmvc+Mybatis）框架整合搭建

好，廢話不多說，直接開篇。

這次的框架整合是根據自己轉載的一篇博客經過自己加工縮編而成的，除了三大框架加一個日誌輸出外沒有別的東西，是非常基礎的一篇框架搭配示例，所以稱爲1.0版，之後可能會在這篇基礎上增加其他非常實用的功能，來完善這個框架，爭取能達到類似正式項目開發中所用到的那樣。

這裏就不介紹這三個框架各自的相關知識了，不熟悉的可以查找相關資料自行查閱，咱們這就開始。

實際上，因爲後邊經歷了幾次完善，以下代碼或許會有些許變更，每次變更，源代碼下載地址也會同時更新。如果大家發現下載的代碼和下面貼的不一致，無需奇怪。功能都能實現，貼出來的只是最簡單，最初的版本。

1、用myeclipse創建web工程，目錄如下，引入jar包

2、建表，表結構如下

3、創建實體類Count.java

package com.panda.entity;

public class Count {
	private int id;
	private String user_name;
	private String user_id;
	private int user_count;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getUser_name() {
		return user_name;
	}
	public void setUser_name(String user_name) {
		this.user_name = user_name;
	}
	public String getUser_id() {
		return user_id;
	}
	public void setUser_id(String user_id) {
		this.user_id = user_id;
	}
	public int getUser_count() {
		return user_count;
	}
	public void setUser_count(int user_count) {
		this.user_count = user_count;
	}
	
	public Count() {
		super();
		// TODO Auto-generated constructor stub
	}
	
	public Count(int id, String user_name, String user_id, int user_count) {
		super();
		this.id = id;
		this.user_name = user_name;
		this.user_id = user_id;
		this.user_count = user_count;
	}
	public Count(String user_name, String user_id, int user_count) {
		super();
		this.user_name = user_name;
		this.user_id = user_id;
		this.user_count = user_count;
	}
	@Override
	public String toString() {
		return "Count [id=" + id + ", user_name=" + user_name + ", user_id="
				+ user_id + ", count=" + user_count + "]";
	}
	
}

4、接口CountMapper.java

package com.panda.dao;

import com.panda.entity.Count;

public interface CountMapper {
	void addInfo(Count count);
	Count serchOne(int id);
}

5、mapper文件CountMapper.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.panda.dao.CountMapper">
	<insert id="addInfo" parameterType="Count" >
		insert into count_money values((select nvl(max(id),0)+1 from count_money),#{user_id},#{user_name},#{user_count}) 
	</insert>
	<select id="serchOne" parameterType="int" resultType="Count">
		select * from count_money where id = #{id}
	</select>
</mapper>

6、service文件CountService.java

package com.panda.service;

import com.panda.entity.Count;

public interface CountService {
	public void addInfo(Count count);
	public Count serchOne(int id);
}

7、service實現類CountServiceImpl.java

package com.panda.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.panda.dao.CountMapper;
import com.panda.entity.Count;
import com.panda.service.CountService;
@Service("countService")
public class CountServiceImpl implements CountService {
	@Resource
	private CountMapper countMapper;
	@Override
	public void addInfo(Count count) {
		// TODO Auto-generated method stub
		countMapper.addInfo(count);
	}
	@Override
	public Count serchOne(int id) {
		// TODO Auto-generated method stub
		return this.countMapper.serchOne(id);
	}

}

8、測試類文件Tes.java

package com.panda.test;

import javax.annotation.Resource;

import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.panda.entity.Count;
import com.panda.service.CountService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring-mybatis.xml"})
public class Tes {
//	private ApplicationContext ac=null;
//	@Before
//	public void setUp() throws Exception {
//		ac=new ClassPathXmlApplicationContext("spring-mybatis.xml");
//	}
	@Resource
	private CountService countService=null;
	 private static Logger logger = Logger.getLogger(Tes.class);  
	int i = 1;
	@Test
	public void test1() {
//		CountServiceImpl countService = (CountServiceImpl)ac.getBean("countService");
		Count coun=countService.serchOne(i);
		logger.info(coun);
		System.out.println(coun);
	}

}

9、配置文件spring-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>

</beans>

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

log4j.properties

OK,spring 和 mybatis框架搭建完成可以進行測試了

測試結果如下這表示沒問題

接下來完成和Springmvc的整合

10、編寫一個配置文件springmvc.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: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/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
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">


	<context:component-scan base-package="com.panda.controller"></context:component-scan> 
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="WEB-INF/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>       
</beans>

11、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  version="2.5"
  id="SSM">
  
  <servlet>
    <servlet-name>springDispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springDispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <servlet>
  	<servlet-name>Jersey REST Service</servlet-name>
  	<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
 	<init-param>
 	<param-name>com.sun.jersey.config.property.packages</param-name>
 	<param-value>com.gontuseries.university</param-value>
 	</init-param>
  </servlet>
  <!-- 引入spring-mybatis配置文件 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:spring-mybatis.xml</param-value>
  </context-param>
  <!-- 編碼過濾 -->
  <filter>
  	<filter-name>encodingFilter</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>encodingFilter</filter-name>
  	<url-pattern>/*</url-pattern>
  </filter-mapping>
  <!-- spring監聽器 -->
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 防止Spring內存溢出監聽器 -->  
    <listener>  
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>  
    </listener>  
</web-app>

12、最後一步，寫一個Controller類PandaController.java

package com.panda.controller;

import javax.annotation.Resource;

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

import com.panda.entity.Count;
import com.panda.service.CountService;

@Controller
@RequestMapping	
public class PandaController {
	@Resource
	private CountService service;
	@RequestMapping("/show.hello")
	public String show(Model model){
		Count count = service.serchOne(1);
		model.addAttribute("count", count);
		return "hello";
	}
}

好了，三大框架已經整合完畢，進行最後的整體測試
首先在index.jsp中寫個登錄FORM表單，再寫一個返回界面success.jsp

登陸測試，實現跳轉，顯示數據

好，成功。
