下图是整个工程的结构图:
接下来我们分别介绍每个配置文件:
1. web.xml
web.xml主要是用于配置spring MVC的分发器以及listener(监听器)
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>PregnantProject</display-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> WEB-INF/applicationContext.xml, WEB-INF/controller_config/controller-config.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
2. applicationContext.xml
在applicationContext中主要配置了spring的事务管理器, 视图解析器, 还有就是数据库连接设置信息。数据库的设置信息也可以配置在database.properties当中,在这里我省去了这一步骤。
<?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: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-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <!--事务管理DataSourceTransactionManager--> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property> <property name="prefix" value="/WEB-INF/views/"></property> <property name="suffix" value=".jsp"></property> </bean> <!-- 异常解析器 --> <bean id="simpleMappingExceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <property name="exceptionMappings"> <props> <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">common/fileerror</prop> </props> </property> </bean> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" destroy-method="close"> <property name="driverClassName"> <value>com.mysql.jdbc.Driver</value> </property> <property name="username"> <value>root</value> </property> <property name="password"> <value>12456</value> </property> <property name="url"> <value>jdbc:mysql://127.0.0.1:3306/pregnant</value> </property> </bean> </beans>
sqlMapConfig.xml
这个文件很简单,就是ibatis的数据库表操作的配置。详细内容如下:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"> <sqlMapConfig> <sqlMap resource="com/pregnant/config/bean/UserBaseinfo.xml"/> </sqlMapConfig>
UserBaseInfo.xml对应的是ibatis对于数据库model的映射以及操作处理,在这里也把配置操作贴出来给大家:
UserBaseInfo.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://www.ibatis.com/dtd/sql-map-2.dtd"> <sqlMap namespace="UserBase"> <typeAlias alias="UserBaseInfo" type="com.pregnant.model.UserBaseInfo"/> <select id="getAllPerson" resultClass="UserBaseInfo"> SELECT * FROM user_baseInfo; </select> <insert id="insertOneUser" parameterClass="java.util.Map"> insert into user_baseInfo values(#userName#,#userEmail#,#userPhone#,#userPasswd#) </insert> <select id="getUserByEmail" resultClass="UserBaseInfo"> select * from user_baseInfo where userEmail = #email# </select> </sqlMap>
上面也介绍完了ibatis的接触配置,那么下面我们将介绍工程各个层级之间的配置:
userbaseinfo_DAO.xml
在这里我们配置了SqlMapClientFactoryBean, 它完成了spring 与ibatis的结合。这里不多讲了,大家自己看配置文件一下就明白了。
<?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: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-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <import resource="../applicationContext.xml"/> <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> <property name="dataSource"> <ref bean="dataSource"/> </property> <property name="configLocation"> <value>WEB-INF/dao_config/sqlMapConfig.xml</value> </property> </bean> <bean id="userBaseInfoDao" class="com.pregnant.daoImpl.UserBaseInfoDaoimpl"> <property name="sqlMapClient" ref="sqlMapClient"/> </bean> </beans>
配置到这里我们应该吧DAO层的一个类的代码贴出来,让大家看看如何调用spring提供的ORM来操作数据库。从配置文件中已经可以看出就是通过sqlmapclient来进行。
package com.pregnant.daoImpl; import java.util.List; import java.util.Map; import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport; import com.pregnant.dao.IUserBaseInfoDao; import com.pregnant.model.UserBaseInfo; public class UserBaseInfoDaoimpl extends SqlMapClientDaoSupport implements IUserBaseInfoDao{ public List<UserBaseInfo> getAllUser(){ List<UserBaseInfo> list = getSqlMapClientTemplate().queryForList("UserBase.getAllPerson"); return list; } @Override public UserBaseInfo getUserByEmail(String email) { UserBaseInfo oneUser = (UserBaseInfo) getSqlMapClientTemplate().queryForObject(email); return oneUser; } @Override public void insertUserbaseInfo(Map info) { getSqlMapClientTemplate().insert("insertOneUser", info); return; } }
接下来的SERVCE层和controller实际上就是利用spring的IOC来注入前一层次的类进行业务操作。这里不做过多介绍只是把代码贴给大家:
one-service.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: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-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <import resource="../dao_config/userbaseinfo_dao.xml"/> <bean id="userBaseInfoService" class="com.pregnant.serviceImpl.UserBaseInfoServiceImpl"> <property name="userBaseInfoDao"> <ref bean="userBaseInfoDao"/> </property> </bean> </beans>
controller.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: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-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <import resource="../service_config/one_service.xml"/> <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="userBaseHandle.do">userBaseInfoController</prop> </props> </property> </bean> <bean id="paraMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver"> <property name="paramName" value="whichMethod"/> </bean> <bean id="userBaseInfoController" class="com.pregnant.controller.UserBaseInfoController"> <property name="methodNameResolver"> <ref bean="paraMethodResolver"/> </property> <property name="userBaseInfoService"> <ref bean="userBaseInfoService"/> </property> </bean>
在controller层为了减少java类的生成,我们利用了spring方法多处理器来进行方法的映射。
值此整个工程配置文件结束。希望对大家有点帮助。
