idea中ssm(spring-spring mvc-mybatis)框架搭建
来源：互联网 发布：php getcontents 编辑：程序博客网 时间：2024/06/07 17:49
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

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" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <!-- 扫描组件 --> <context:component-scan base-package="com.wangjianxin.front.controller"> </context:component-scan> <aop:aspectj-autoproxy proxy-target-class="true"/> <!-- 视图解释 --> <!--默认的注解映射的支持--> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg value="UTF-8"/> </bean> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="objectMapper"> <bean class="com.github.miemiedev.mybatis.paginator.jackson2.PageListJsonMapper"/> </property> <property name="supportedMediaTypes"> <list> <value>text/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!--设置静态资源handler --> <mvc:default-servlet-handler/> <!-- 支持上传文件 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/> <!-- @ResponseBody方法异常处理--> <bean id="mappingJackson2HttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="objectMapper"> <bean class="com.github.miemiedev.mybatis.paginator.jackson2.PageListJsonMapper"/> </property> </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" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <context:component-scan base-package="com.wangjianxin.service"/> <context:component-scan base-package="com.google.code.kaptcha"/> <!--<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:list> <beans:value>classpath:jdbc.properties</beans:value> </beans:list> </beans:property> </beans:bean> <context:annotation-config/> <beans:bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource"> <beans:property name="driver" value="com.mysql.jdbc.Driver"/> <beans:property name="driverUrl" value="${jdbcUrl}" /> <beans:property name="user" value="${username}" /> <beans:property name="password" value="${password}" /> <beans:property name="alias" value="Pool_dbname" /> <beans:property name="houseKeepingSleepTime" value="90000" /> <beans:property name="prototypeCount" value="0" /> <beans:property name="maximumConnectionCount" value="50" /> <beans:property name="minimumConnectionCount" value="2" /> <beans:property name="simultaneousBuildThrottle" value="50" /> <beans:property name="maximumConnectionLifetime" value="14400000" /> <beans:property name="houseKeepingTestSql" value="select CURRENT_DATE" /> </beans:bean> <beans:bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <beans:property name="dataSource" ref="dataSource"/> <beans:property name="configLocation" value="classpath:mybatis-config.xml"/> <beans:property name="mapperLocations" value="classpath:/mapping/*.xml"/> <beans:property name="typeAliasesPackage" value="com.wangjianxin.service.model"/> <beans:property name="typeAliases" value="org.springframework.util.LinkedCaseInsensitiveMap"/> </beans:bean> <beans:bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <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"><configuration> <settings> <!--<setting name="cacheEnabled" value="true" />--> <!--<setting name="lazyLoadingEnabled" value="true" />--> <!--<setting name="aggressiveLazyLoading" value="true"/>--> <!-- 这个配置使全局的映射器启用或禁用缓存 --> <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="lazyLoadingEnabled" value="true"/> <!-- 当启用时，有延迟加载属性的对象在被调用时将会完全加载任意属性。否则，每种属性将会按需要加载 --> <setting name="aggressiveLazyLoading" value="true"/> <!-- 允许或不允许多种结果集从一个单独的语句中返回（需要适合的驱动） --> <setting name="multipleResultSetsEnabled" value="true"/> <!-- 使用列标签代替列名。不同的驱动在这方便表现不同。参考驱动文档或充分测试两种方法来决定所使用的驱动 --> <setting name="useColumnLabel" value="true"/> <!-- 允许JDBC支持生成的键。需要适合的驱动。如果设置为true则这个设置强制生成的键被使用，尽管一些驱动拒绝兼容但仍然有效（比如Derby） --> <setting name="useGeneratedKeys" value="true"/> <!-- 指定MyBatis如何自动映射列到字段/属性。PARTIAL只会自动映射简单，没有嵌套的结果。FULL会自动映射任意复杂的结果（嵌套的或其他情况） --> <setting name="autoMappingBehavior" value="PARTIAL"/> <!-- 配置默认的执行器。SIMPLE执行器没有什么特别之处。REUSE执行器重用预处理语句。BATCH执行器重用语句和批量更新 --> <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=mysqljdbcUrl=jdbc\:mysql\://localhost\:3306/ssm?autoReconnect\=true&useUnicode\=true&characterEncoding\=UTF-8username=rootpassword=rootbonecp.idleConnectionTestPeriod=60bonecp.idleConnectionTestPeriodInMinutes=5bonecp.idleMaxAgeInMinutes=10bonecp.idleMaxAge=60bonecp.partitionCount=3bonecp.minConnectionsPerPartition=2bonecp.maxConnectionsPerPartition=50bonecp.acquireIncrement=3bonecp.statementsCacheSize=50bonecp.releaseHelperThreads=3bonecp.defaultAutoCommit=truessm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" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <listener> <listener-class>com.github.miemiedev.mybatis.paginator.CleanupMybatisPaginatorListener</listener-class> </listener> <filter> <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping></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，

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。
