idea中ssm(spring-spring mvc-mybatis)框架搭建

我的idea是13.1.3

首先点击 File - New Project - 选择maven ，并且在右面选择maven-archtype-webapp选项，如图所示



点击next后，出现填写GroupId和Artifactid，一般GroupId写com.***.项目，Artifactid写你的项目名称



然后点击next



点击next



Project name 项目名称，location项目地址，随后点击finish,如果未创建例如我的E盘csdn文件夹，会提示是否创建，点OK

随后idea进行下载目录结构，如果网络慢的话，可能会等比较长时间。 创建好目录之后提示信息，忽略那条waring...如下图



先看一下项目 目录的结构



现在是一个大的project,我们可以右键csdn项目new 一个Module命名为csdn-front前端模块，在右键new一个Module命名为csdn-service作为数据模块，步骤过程和上面一样，过程略去，（这里面，new的Module也都是maven项目，记得和上述过程一样哦）直接展示new好的目录结构



我这里的csdn-front中的main目录下java目录是自己手动创建的，会发现他是蓝色的，如果刚接触idea不久可能不知道如何创建java目录，还是new 一个文件夹命名为java,然后操作如下图所示



酱紫就是蓝色的java目录了

现在配置pom.文件，打开csdn-front里的pom.xml

将包都下载到本地maven库之后，开始写配置文件

在csdn-front中的resources里new spring config



命名爲spring-servlet，内容如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 	视图解释 -->

</bean>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>

隨後整合mybatis,new xml （步驟和上面一樣）命名為 spring-mybatis

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!--<beans:bean id="ServiceLocator" class="com.wangjianxin.util.ServiceLocator"/>-->

<!--<beans:bean id="Producer" class="com.google.code.kaptcha.Producer" abstract="true"/>-->

<beans:bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<beans:property name="locations">

</beans:bean>

<beans:property name="maximumConnectionLifetime" value="14400000" />
<beans:property name="houseKeepingTestSql" value="select CURRENT_DATE" />
</beans:bean>

<beans:bean id="sqlSessionFactory"

<beans:property name="configLocation" value="classpath:mybatis-config.xml"/>

<beans:property name="basePackage" value="com.wangjianxin.service.dao"/>
<beans:property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
</beans:bean>
</beans:beans>

继续新建xml文件 命名为mybatis-config 如下（这个xml里的settings借鉴了网上的一篇文章，，，）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-config.dtd">

<!--<setting name="aggressiveLazyLoading" value="true"/>-->

<setting name="cacheEnabled" value="true"/>
<!-- 全局启用或禁用延迟加载。当禁用时，所有关联对象都会即时加载 -->

<setting name="defaultExecutorType" value="SIMPLE"/>
<!-- 设置超时时间，它决定驱动等待一个数据库响应的时间 -->
<setting name="defaultStatementTimeout" value="25000"/>
</settings>
<plugins>
<plugin interceptor="com.github.miemiedev.mybatis.paginator.OffsetLimitInterceptor">
<property name="dialectClass" value="com.github.miemiedev.mybatis.paginator.dialect.MySQLDialect"/>
</plugin>
</plugins>
</configuration>

借着配置配置jdbc.properties 如下

type=mysql
jdbcUrl=jdbc\:mysql\://localhost\:3306/ssm?autoReconnect\=true&useUnicode\=true&characterEncoding\=UTF-8
username=root
password=root
bonecp.idleConnectionTestPeriod=60
bonecp.idleConnectionTestPeriodInMinutes=5
bonecp.idleMaxAgeInMinutes=10
bonecp.idleMaxAge=60
bonecp.partitionCount=3
bonecp.minConnectionsPerPartition=2
bonecp.maxConnectionsPerPartition=50
bonecp.acquireIncrement=3
bonecp.statementsCacheSize=50
bonecp.releaseHelperThreads=3
bonecp.defaultAutoCommit=true

ssm是我的数据库名字，下面root是账号和密码

最后配置web xml文件

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

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

</web-app>

最后看一下csdn-front里的resources的文件



随后开始创建controller 和service

创建controller包，new class文件

package com.wangjianxin.front.controller;

import com.wangjianxin.service.manager.StudentManager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.List;
/**
* Created by wangjianxin on 2016/10/31.
*/
@Controller
@RequestMapping("/ssm")
public class CsdnController {

@Autowired
private StudentManager studentManager;

@RequestMapping(value = "/csdn.json",method = RequestMethod.GET)
@ResponseBody
public String csdn(){
List lsit =   studentManager.selectall();
return lsit.toString();
}

@RequestMapping(value = "/csdn.html")
public String html(){
return "csdn";
}

}

这样一个简单的controller类就建立了，例如要访问csdn.json这个接口的url就可以写成： /ssm/csdn.json。 可以理解下@RequestMapping这个注解

利用@Autowired引入manager 调用manager接口的方法

随后在csdn-service中建立文件夹和类如图



想必这些类目大家都懂得，dao层中的接口方法名和mapping中的xml映射相对应，

StudentManager:

package com.wangjianxin.service.manager;
import com.wangjianxin.service.model.Student;

import java.util.List;

/**
* Created by wangjianxin on 2016/10/26.
*/
public interface StudentManager {
List selectall();
}

StudentManagerImpl:

package com.wangjianxin.service.manager.impl;

import com.wangjianxin.service.dao.StudentMapper;
import com.wangjianxin.service.manager.StudentManager;
import com.wangjianxin.service.model.Student;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
* Created by wangjianxin on 2016/10/26.
*/
@Service
public class StudentManagerImpl implements StudentManager{

@Autowired
private StudentManager studentManager;
@Override
public List selectall() {
List lsit  = studentManager.selectall();
return lsit;
}
}

StudentMapper:

package com.wangjianxin.service.manager;
import com.wangjianxin.service.model.Student;

import java.util.List;

/**
* Created by wangjianxin on 2016/10/26.
*/
public interface StudentManager {
List selectall();
}

StudentMapping.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.wangjianxin.service.dao.StudentMapper" >
<resultMap id="BaseResultMap" type="com.wangjianxin.service.model.Student" >
<id column="id" property="id" jdbcType="INTEGER" />
<result column="name" property="name" jdbcType="VARCHAR" />
<result column="age" property="age" jdbcType="INTEGER" />
<result column="hobby" property="hobby" jdbcType="VARCHAR" />
</resultMap>
<sql id="Base_Column_List" >
id, name, age, hobby
</sql>
<select id="selectall" resultMap="BaseResultMap" parameterType="java.lang.Integer" >
select
<include refid="Base_Column_List" />
from student
</select>
</mapper>

model懒的写上来了，就那几个属性，在数据库中随便的建的表

在csdn的WEB-INF的jsp文件夹下面建立csdn.jsp文件

hello csdn 哈哈~

<input type="button" onclick="getStudent()" value="获取数据" />
<input type="text" id="csdn"/>

<script>
function getStudent(){
$.ajax({
url:"/ssm/csdn.json",
type:"get",
success:function (data){
$('#csdb').val(data);
}
})
}
</script>
</body>
</html>

写了个ajax和controller交互。

首先编译项目，cmd 命令切换到csdn项目的目录，mvn install

随后编译成功后可以在idea中的maven Project选项栏里找到csdn-front里的Plugins-jetty-jetty:run运行。

输入地址localhost:8080/ssm/csdn.html
