SSM三大框架的整合
搭建整合环境
1.整合说明：SSM整合有很多种方式，我们采用XML+注解的方式
2.整合思路：
- 先搭建整合的环境
- 先把Spring的配置搭建完成
- 使用Spring整合SpringMVC框架
- 使用Spring整合MyBatis框架
3.创建数据库和表结构
DDL
4.创建maven工程（聚合和拆分）
- 创建ssm_parent父工程(打包方式选择pom，必须)
- 创建ssm_web子模块(打包方式是war包)
- 创建ssm_service子模块(打包方式是jar包)
- 创建ssm_dao子模式(打包方式是jar包)
- 创建ssm_domain子模块(打包方式是jar包)
- web依赖于service,service依赖于dao,dao依赖于domain
- 再ssm_parent的pom.xml文件中引入坐标依赖
pom.xml

再创建Account的三层结构
编写Spring框架
1.配置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.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<!-- 开启注解扫描,要扫描的是service和dao层的注解，要忽略web(Controller)层注解，因为web层让SpringMVC框架去管理 -->
<context:component-scan base-package="cn">
<!-- 配置要忽略的注解 -->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
</beans>
2.测试一下Spring是否配置成功
AccountServiceImpl.java
package cn.service.impl;
import cn.domain.Account;
import cn.service.AccountService;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("accountService")
public class AccountServiceImpl implements AccountService {
@Override
public List<Account> findAll() {
System.out.println("业务层：查询所有账户...");
return null;
}
@Override
public void saveAccount(Account account) {
System.out.println("业务层：保存账户...");
}
}
TestSpring.java
package cn.test;
import cn.service.AccountService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestSpring {
@Test
public void run1(){
//加载配置文件
ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
//获取对象
AccountService as = (AccountService) ac.getBean("accountService");
//调用方法
as.findAll();
}
}
3.引入一个log4j.properties
# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE debug info warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE
# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
4.Spring配置成功控制台输出
编写SpringMVC框架

return "list";
}
}
4.成功页面
编写Mybatis框架
1.配置SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration

dao.saveAccount(account);
//提交事务
session.commit();
//释放资源
session.close();
in.close();
}
}
6.数据库插入成功页面
Spring整合MyBatis框架
1.配置applicationContext.xml就是让spring去配置连接池代替了mybatis中的SqlMapConfig.xml,就可以把SqlMapConfig.xml删掉

2.给AccountDao.java加注释方法
package cn.dao;
import cn.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
import java.util.List;
/**

@Repository
public interface AccountDao {
//查询所有账户信息
@Select("select * from account")
public List<Account> findAll();
//保存账户信息
@Insert("insert into account (name,money) values (#{name},#{money})")
public void saveAccount(Account account);
}
3.修改AccountServiceImpl.java
package cn.service.impl;
import cn.dao.AccountDao;
import cn.domain.Account;
import cn.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

public class AccountServiceImpl implements AccountService {
@Autowired
private AccountDao accountDao;
@Override
public List<Account> findAll() {
System.out.println("业务层：查询所有账户...");
return accountDao.findAll();
}
@Override
public void saveAccount(Account account) {
System.out.println("业务层：保存账户...");
accountDao.saveAccount(account);
}
}
4.修改AccountController.java
package cn.controller;
import cn.domain.Account;
import cn.service.AccountService;
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 java.util.List;
/**

@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private AccountService accountService;
@RequestMapping("/findAll")
public String findAll(Model model){
System.out.println("表现层：查询所有账户信息...");
// 调用service的方法
List<Account> list = accountService.findAll();
model.addAttribute("list",list);
return "list";
}
}
5.修改List.jsp
