ssm整合丐版

写在开头的话：

难者不会会者不难，麻烦冗长

今日份的小曲是童丽阿姨的女儿情开始，她的歌温润婉转，少妇味。第一次听到她的女儿情时，直呼这是在女儿国录的音。

忘了发了，写了有好两天了，因为tyora到论坛图片需要手动点，当时就懒得上传，之后就忘了。

新建maven工程

创建文件夹，让它有一个大致的文件结构。

实体类和库一起写：

package zzzzmdzz.pojo;import java.io.Serializable;public class User implements Serializable {//序列化private Integer id;private Integer no;private String name;private String pass;private String sex;private Integer age;private String dataTime;
//getset

dao和service,这里写完可以测试一下Spring框架，我为了让正文精简一点，私底下的测试不贴上来，你就知道写个applicationContext.xml和test执行就行。

package zzzzmdzz.dao;import zzzzmdzz.pojo.User;import java.util.List;public interface UserDao {public List<User> findAll();public void saveUser(User user);
}

service

package zzzzmdzz.service;import zzzzmdzz.pojo.User;import java.util.List;public interface UserService {public List<User> findAll();//查询全部public void saveUser(User user);//保存
}

package zzzzmdzz.service.Impl;import org.springframework.stereotype.Service;
import zzzzmdzz.pojo.User;
import zzzzmdzz.service.UserService;import java.util.List;@Service("userService")
public class UserServiceImpl implements UserService {@Overridepublic List<User> findAll(){System.out.println("查询全部");return null;}@Overridepublic void saveUser(User user){System.out.println("保存");}
}

controller:

package zzzzmdzz.controller;public class UserController {public String findAll(){System.out.println("Fand All");return "list";}
}

web.xml:

springmvc.xml

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

<!--    <mvc:resources mapping="/js/**" location="/js/"/>--><!-- 开启SpringMVC注解模式 --><mvc:annotation-driven/><!-- 静态资源默认servlet配置 --><mvc:default-servlet-handler/></beans>

现在就可以写个index.jsp测试了

配置tomcat，执行。

现在开始，往这个框架里加东西。

web.xml加入监听器

<!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!--设置配置文件的路径--><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param>

controller加入调用：

public class UserController {@Autowiredprivate UserService userService;@RequestMapping("/user/findAll")public String findAll(){System.out.println("Fand All");List<User> list= userService.findAll();return "list";

代码不完整，自行补全吧，头头尾尾的。

在测试一下，控制台能看到这个：

至此，spring，springmvc写好。现在写MyBatis。

dao里加注解，这就是sql语句了，batis你好强大！

@Repository
public interface UserDao {
@Select("select * from user")public List<User> findAll();@Insert("insert into user (no,name,pass,sex,age) value(#{no},#{name},#{pass},#{sex},#{age})")public void saveUser(User user);

数据库连接配置，里面的参数也按个人口味酌情更改

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis//DTD Config 3.0//EN"".dtd"><configuration><environments default="mysql"><environment id="mysql"><transactionManager type="JDBC"/><dataSource type="POOLED"><property name="driver" value="com.mysql.jdbc.Driver"/><property name="url" value="jdbc:mysql:///ssmuser"/><property name="username" value="root"/><property name="password" value="x5"/></dataSource></environment></environments><mappers><package name="zzzzmdzz.dao"/></mappers>
</configuration>

写个batis的test，并测试

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;
import zzzzmdzz.dao.UserDao;
import zzzzmdzz.pojo.User;import java.io.IOException;
import java.io.InputStream;
import java.util.List;public class TestMyBatis {@Testpublic void run2() throws IOException{User user=new User();user.setName("yyds");user.setAge(114514);user.setNo(4);user.setPass("lbwnb");user.setSex("futa");// 加载配置文件InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");// 创建SqlSessionFactorySqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);// 创建SqlSessionSqlSession session = factory.openSession();//获取代理对象UserDao dao=session.getMapper(UserDao.class);//保存dao.saveUser(user);//提交sessionmit();//关闭session.close();in.close();}public void run3() throws Exception{InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");SqlSessionFactory fac=new SqlSessionFactoryBuilder().build(in);SqlSession se=fac.openSession();UserDao dao=se.getMapper(UserDao.class);List<User> list=dao.findAll();for (User user:list){System.out.println(user);}se.close();in.close();}
}

执行完了就会在数据库里加这么一项新的，有时候需要刷新一下数据库。

下一步，将mybatis的配置转移进spring。

即sqlmapconfig.xml里的数据库，连接池，dao接口包，装进applicationContext.xml.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""xmlns:xsi=""xmlns:context=""xmlns:tx=""xsi:schemaLocation="://www.springframework/schema/beans/spring-beans.xsd://www.springframework/schema/context/spring-context.xsd://www.springframework/schema/aop/spring-aop.xsd://www.springframework/schema/tx/spring-tx.xsd"><!-- 扫描service包下所有使用注解的类型 --><context:component-scan base-package="zzzzmdzz">

</beans>

自己看看区别，把缺的东西粘过去吧。

在UserServiceImpl里添加Dao的调用。

public class UserServiceImpl implements UserService {//@Override@Autowired
//    UserService userService;private UserDao userDao;public List<User> findAll(){System.out.println("查询全部");return userDao.findAll();}

就是定义了个UserDao,然后return到findall。

controller层添加调用：

完善list.jsp,让它能输出一些东西。

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8" %>
<%String path = request.getContextPath();String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
<%@ taglib prefix="c" uri="" %><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head><base href="<%=basePath%>"><title>My JSP page</title>
</head><body>
<h2>我是你爹!</h2>
<h1>find all</h1>
<c:forEach items="${list}" var="user">${user.name}
</c:forEach>
</body>
</html>

yysy,html的“c”语言我是不会写的，这是抄来的。

tomcat测试一下。

到这里基本就是完成了，剩下的就是配置事务，是在能跑起来的情况下的扩展。

applicationContext.xml里再加一些配置。

这些也都是有固定依赖的定式，上网冲浪复制粘贴就有了：

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

<!--配置事务通知-->
<tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="find*" read-only="true"/><tx:method name="*" isolation="DEFAULT"/></tx:attributes>
</tx:advice><!--配置AOP增强-->
<aop:config><aop:advisor advice-ref="txAdvice" pointcut="execution(* zzzzmdzz.service.Impl.*ServiceImpl.*(..))"/>
</aop:config>

这里的文件目录记得改。

完善一下index：

<%@ page contentType="text/html; charset=UTF-8" language="java" %>
<html>
<body><a href="user/findAll">点击一键找爹</a><h3>test</h3><form action="user/save" method="post">name：<input type="text" name="name" /><br/>pass: <input type="text" name="pass" /><br/>sex:  <input type="text" name="sex" /><br/>age: <input type="text" name="age"/><br/><input type="submit" value="保存"/><br/>
</form>
</body>
</html>

去service和controller把保存也写了：

@RequestMapping("/user/save")
public void save(User user, HttpServletRequest request,HttpServletResponse response)throws IOException{userService.saveUser(user);response.sendRedirect(request.getContextPath()+"/user/findAll");return;
}

测试：

完成。

最后是扯淡，与正文无关，不想看的可以直接退了。

1，感谢这些人的教程：

=1001.2014.3001.5501

=1001.2014.3001.5501

我写着玩意也不能算是教程，毕竟都是参考上面这些人，综合写出来的，只能说进攻参考吧。

2，遇到了很多问题，全靠面向csdn解决，最感谢的是这份资料，帮我解决这问题，让我早睡两个小时，万分感谢：

无意冒犯，仅做分享，如果原作者介意的话，给我留个言马上就删。

3，jsp里的大标题，本来我是打算写个helloworld啥的，当时我同桌捅咕过来：“我是你爹！”然后我就脑子一热写进来了。
