Maven+SpringMvc4+MyBatis+Jdk8+整合ssm架构

62 阅读 0 评论
我是靠谱客的博主 小巧大树，最近开发中收集的这篇文章主要介绍Maven+SpringMvc4+MyBatis+Jdk8+整合ssm架构，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

 

 

这篇文章的ssm架构事务是xml形式的，其实都是差不多，其实公司用注解事务更多一些，因为容易控制。

代码我也是放在git上面了。

如果你不想看文章，可以直接下载源码浏览，

1、https://gitee.com/redpigstu/ssm_demo_xml

2、https://gitee.com/imjcoder/ssm_demo_interface

1、在eclipse中新建maven项目
新建完你的项目如图：

这时候java、test都没有，需要简单配置下，右击项目选择最后一个属性：

做一些配置

之后你的项目会如下图：

2、下面开始配置把相关的pom里面的依赖加进来

		<!-- 指定 MyBatis 如何自动映射 数据基表的列 NONE：不隐射　PARTIAL:部分  FULL:全部  -->  
		<setting name="autoMappingBehavior" value="PARTIAL"/>
		<!-- 这是默认的执行类型  （SIMPLE: 简单； REUSE: 执行器可能重复使用prepared statements语句；BATCH: 执行器可以重复执行语句和批量更新）  -->
		<setting name="defaultExecutorType" value="SIMPLE"/>
		<!-- 使用驼峰命名法转换字段。 -->
		<!-- <setting name="mapUnderscoreToCamelCase" value="true"/> -->
		<!-- 设置本地缓存范围 session:就会有数据的共享  statement:语句范围 (这样就不会有数据的共享 ) defalut:session -->
        <setting name="localCacheScope" value="SESSION"/>
        <!-- 设置但JDBC类型为空时,某些驱动程序 要指定值,default:OTHER，插入空值时不需要指定类型 -->
        <setting name="jdbcTypeForNull" value="NULL"/>
	</settings>
</configuration>

4、配置spring相关

在src/main/resources下面新建文件夹spring

   ①、新建文件名：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:p="http://www.springframework.org/schema/p"

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

	<!-- 扫描到有@Component @Controller@Service等这些注解的类 ,则把这些类注册为bean -->
	<!-- spring不要扫MVC的controller,否则引起事务失效 -->
	<context:component-scan base-package="com">
		<context:exclude-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>
	
	<!-- 数据库连接池 :dataSource -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close">
		<property name="driverClass" value="com.mysql.jdbc.Driver" />

  		<!-- 别名扫描包 -->
  		<property name="typeAliasesPackage" value="com.entity"/>
	</bean>
	
	
	<!-- 配置自动生成接口的实现类  
	 配置 转换器，对于在basePackage设置的包（包括子包）下的接口类，如果在Mapper.xml文件中定义过，
	将被转换成spring的BEAN，在调用 的地方通过@Autowired方式将可以注入接口实例-->
	
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
		<property name="basePackage" value="com.dao"/>
	</bean>

</beans>

    ③、新建文件名：applicationContext-transaction.xml

			<tx:method name="query*" read-only="true" />
			<!--其他方法使用默认事务策略 -->
			<tx:method name="*" />
		</tx:attributes>
	</tx:advice>

	<aop:config>
		<!--pointcut元素定义一个切入点，execution中的第一个星号 用以匹配方法的返回类型，
			这里星号表明匹配所有返回类型。 com.abc.dao.*.*(..)表明匹配com.service包下的所有类的所有 
			方法 -->
		<aop:pointcut id="myPointcut" expression="execution(* com.service.*.*(..))" />
		<!--将定义好的事务处理策略应用到上述的切入点 -->
		<aop:advisor advice-ref="txAdvice" pointcut-ref="myPointcut" />
	</aop:config>
	
</beans>

5、下面开始配置springmvc相关的

  在src/main/resources/ spring文件夹下新建：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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"

	<!-- 同时开启json格式的支持 -->
	<mvc:annotation-driven></mvc:annotation-driven>
	
	<!-- spring mvc 扫描所有的controller 但是不扫描service -->
	<context:component-scan base-package="com">
		<context:include-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
		<context:exclude-filter type="annotation"
			expression="org.springframework.stereotype.Service" />
	</context:component-scan>

	
	<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" /><!--可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑 -->
	</bean>

</beans>

6、配置日志

 

##root logger , local level: debug, output: stdout ##
## root logger: better performance than others   ##
log4j.rootLogger=info,stdout

log4j.appender.F=org.apache.log4j.DailyRollingFileAppender

log4j.logger.java.sql.Statement = DEBUG  
log4j.logger.java.sql.PreparedStatement = DEBUG
log4j.logger.java.sql.ResultSet = DEBUG

7、配置web.xml

 

<?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"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="MyWebApp" version="2.5">
	<display-name>my</display-name>

	<!-- 加载(spring自身的,事务,mybatis)配置文件-->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring/applicationContext*.xml</param-value>

	<!-- 防止spring内存溢出监听器 -->  
	<listener>  
	    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>  
	</listener> 
	
	<!--Spring的ApplicationContext 载入：Spring的监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 加载SpringMVC的配置文件-->
	<servlet>

	</filter>  
	<filter-mapping>  
	    <filter-name>encodingFilter</filter-name>  
	    <url-pattern>/*</url-pattern>  
	</filter-mapping> 
	
	
	
		<!-- 配置session超时时间，单位分钟 -->  
		<session-config>  
		    <session-timeout>60</session-timeout>  
		</session-config>  
		  
		<!-- DEFAULT PAGE -->  
		<welcome-file-list>  
		    <welcome-file>index.jsp</welcome-file>  
		</welcome-file-list>  
</web-app>

8、新建表t_user

 

CREATE TABLE `t_user` (
  `username` varchar(255) NOT NULL,
  `password` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

9、新建实体类User

 

package com.entity;

public class User {
	private String username;  
    private String password;
	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;
	}

}

10、新建mybatis mapper配置文件UserMapper.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.dao.UserDao">  
    <resultMap id="BaseResultMap" type="com.entity.User">  
        <result column="username" property="username" />  
        <result column="password" property="password" />  
    </resultMap>  
  <sql id="Base_Column_List" >  
    username, password  
  </sql>  
  <select id="selectId" resultMap="BaseResultMap" parameterType="java.lang.String" >  
    select   
    <include refid="Base_Column_List" />  
    from t_user  
    where username = #{username,jdbcType=VARCHAR}  
  </select>  
</mapper>

11、创建service接口

 

package com.service;

import org.springframework.stereotype.Service;

import com.entity.User;

@Service
public interface UserService {
	boolean doUserLogin(User user);  

}

12、创建service实现类

 

package com.service;

import java.util.List;

import javax.annotation.Resource;
import javax.annotation.Resources;

import org.springframework.stereotype.Service;

import com.dao.UserDao;
import com.entity.User;

@Service
public class UserServiceImpl implements UserService {
	
	 @Resource
	private UserDao userDao; 

	public boolean doUserLogin(User user) {
		List<User> list = userDao.selectId(user.getUsername());  
        if(list.size() == 0){  
            return false;  
        }else{  
            if(list.get(0).getPassword().equals(user.getPassword())){                 
                return true;  
            }else{  
                return false;  
            }             
        }  
	}

}

13、创建UserDao接口

 

package com.dao;

import java.util.List;

import org.springframework.stereotype.Repository;

import com.entity.User;

@Repository
public interface UserDao{  
    List<User> selectId(String username);  
}


14、创建controller

 

package com.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.entity.User;
import com.service.UserService;

@Controller
@RequestMapping("/test")
/*@ResponseBody */ 
public class LoginController {
	 @Autowired  
	 private UserService userService; //基于接口的,用接口接收
	   
	   @RequestMapping("/login.action") //url  
	   public String dologin(User user, Model model){  
	       if(userService.doUserLogin(user)){ 
	    	   System.out.println(user);	    	   
	           model.addAttribute("successMsg", "登陆成功！");//返回到页面所夹带的参数  
	           model.addAttribute("name", user.getUsername());  
	           return "/success";//返回的页面  
	       }else{  
	           model.addAttribute("failMsg", "用户不存在或密码错误！");  
	           return "/fail";  
	       }     
	   }  
	   
	   

}

至此配置完成，还有前端页面代码没有贴出来，大家需要的话到这里下载：https://gitee.com/redpigstu/ssm_demo_xml
