Struts2+Spring4+myBatis3整合

栏目:htmlcss时间:2016-10-08 15:45:01

终究开始整合了,3大工具各司其职。Struts负责与jsp交互,Spring针对javaBean的生命周期进行管理,myBatis负责数据库部份。

个人认为整合最重要的是找对相应的包,不然包之间便可能出现冲突,然后1直报错。以下是千辛万苦测试成功的包:

配置web.xml

<?xml version="1.0" encoding="UTF⑻"?> <web-app version="2.5" 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_2_5.xsd"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- spring 加载文件配置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- spring监听器配置 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 设置spring字符编码过滤器 --> <filter> <filter-name>characterEncoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF⑻</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置Struts2 --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>

配置applicationContext.xml

<?xml version="1.0" encoding="UTF⑻"?> <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" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 采取注解的方式配置bean --> <context:annotation-config /> <!-- 配置要扫描的包 --> <context:component-scan base-package="gyt.frame.first"></context:component-scan> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="configLocation" value="classpath:MyBatis.xml" /> <property name="dataSource" ref="dataSource" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="url" value="jdbc:mysql://localhost:3306/SSM" /> <property name="username" value="root" /> <property name="password" value="123456" /> <property name="maxActive" value="100" /> <property name="maxIdle" value="5" /> <property name="minEvictableIdleTimeMillis" value="300000" /> <property name="timeBetweenEvictionRunsMillis" value="120000" /> <property name="validationQuery" value="SELECT 1" /> <property name="testWhileIdle" value="true" /> <property name="testOnReturn" value="true" /> <property name="testOnBorrow" value="true" /> </bean> <bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean"> <property name="sqlSessionFactory" ref="sqlSessionFactory" /> <property name="mapperInterface" value="gyt.frame.first.UserDao" /> </bean> <!-- 配置mybatis数据处理的方式,共4种方式,这里采取MapperScannerConfigurer方式 --> <!-- SqlSessionTemplate 这个需要写配置文件,在实现类中注入sqlsession,再使用sqlsession,是细颗粒控制 SqlSessionDaoSupport 这个只需要在实现类中继承特殊类就能够使用sqlsession MapperFactoryBean 这个要写配置文件,把对应的所有接口在配置文件中援用便可,无需写实现类 MapperScannerConfigurer 这个要写配置文件,只要给出接口所在的包便可,会自动把包中的接口引入,无需写实现类 --> <!-- jdbc初始化数据库 --> <!-- <jdbc:initialize-database data-source="dataSource" ignore-failures="NONE" enabled="true"> <jdbc:script encoding="utf⑻" location="/WEB-INF/db-init.sql"/> </jdbc:initialize-database> --> <!-- 配置哪些方法用甚么样的事务,配置事务的传播特性 --> <!-- <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="pointcut" expression="execution(* D1.serviceimpl.UserServiceImpl.*(..))" /> <aop:advisor advice-ref="log" pointcut-ref="pointcut"/> </aop:config> --> <!-- 配置结束 --> </beans>

applicationContext.xml里的重点:
<context:annotation-config />,写了这句话才能使用注解的方式配置Bean。
<context:component-scan base-package="gyt.frame.first"></context:component-scan>,配置需要扫描的包。如果某个类的头上带有特定的注解@Component,@Repository,@Service,@Controller,就会将这个对象作为Bean注册进Spring容器。扫描多个包用逗号隔开。
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:MyBatis.xml" />
<property name="dataSource" ref="dataSource" />
</bean>
,用于创建工厂Bean。
<bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
<property name="mapperInterface" value="gyt.frame.first.UserDao" />
</bean>
,创建dao bean(只需提供接口不需提供实现类 )。学习于http://blog.csdn.net/hupanfeng/article/details/21454847。

配置struts.xml

<?xml version="1.0" encoding="UTF⑻" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts⑵.1.dtd"> <struts> <!-- 指定默许编码集 ,作用于HttpServletRequest的setCharacterEncoding()和freemarker,vilocity的输出 --> <constant name="struts.i18n.encoding" value="UTF⑻"/> <!-- 当struts配置文件修改时是不是自动加载 --> <constant name="struts.configuration.xmlreload" value="true"/> <!-- 开发模式下打印详细的毛病信息,默许为false --> <constant name="struts.devMode" value="true"/> <!-- 标准的UI主题,默许的UI主题为xhtml,可以为simple,xhtml或ajax --> <constant name="struts.ui.theme" value="xhtml"/> <package name="test" namespace="/test" extends="struts-default"> <action name="hello" class="gyt.frame.first.HelloAction"> <result name="success">/jsps/HelloAction.jsp</result> </action> </package> <package name="user" namespace="/user" extends="struts-default"> <action name="UserAction" class="gyt.frame.first.UserAction"> <result name="success">index.jsp</result> </action> </package> </struts>

配置myBatis.xml

<?xml version="1.0" encoding="UTF⑻"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis⑶-config.dtd"> <configuration> <!-- 映照文件,寄存sql语句的配置文件 --> <mappers> <mapper resource="gyt/frame/first/UserMappers.xml" /> </mappers> </configuration>

配置log4j.properties

log4j.rootLogger=info,A1 log4j.logger.com.mchange=warn,A1 log4j.additivity.com.mchange=false log4j.logger.org.hibernate=warn,A1 log4j.additivity.org.hibernate=false log4j.logger.com.ibatis=warn,A1 log4j.additivity.com.ibatis=false # ConsoleAppender log4j.appender.A1=org.apache.log4j.ConsoleAppender log4j.appender.A1.layout=org.apache.log4j.PatternLayout log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH\:mm\:ss,SSS} [%c]-[%p] %m%n # \u6253\u5370sql log4j.logger.org.apache.ibatis=debug log4j.logger.java.sql.Connection=debug log4j.logger.java.sql.Statement=debug log4j.logger.java.sql.PreparedStatement=debug log4j.logger.java.sql.ResultSet=debug #com.frame log4j.logger.com.frame=debug

创建表

CREATE TABLE `user` ( `UserNo` varchar(10) NOT NULL, `DepartmentNo` varchar(10) DEFAULT NULL, `UserName` varchar(10) DEFAULT NULL, `Password` char(16) DEFAULT NULL, `Email` varchar(40) DEFAULT NULL, PRIMARY KEY (`UserNo`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

新建1个action类UserAction.java

/* Action注解单例问题 交有spring管理后,action默许是单例模式。但是项目不能全部都采取单例,使用我们需要加入相干注解切换为非单例: 在action上面配置,@Scope("prototype") ,每一个要求都会new1个新的实例 */ @Controller @Scope("prototype") public class UserAction extends ActionSupport { /** * */ private static final long serialVersionUID = 1L; @Autowired //@Resource(name="userservice") private UserService userservice;// 使用@Autowired,要写setter方法。 private User user=new User();//不写New,将报空指针 public User getUser() { return user; } public void setUser(User user) { this.user = user; } public UserService getUserservice() { return userservice; } public void setUserservice(UserService userservice) { this.userservice = userservice; } public static long getSerialversionuid() { return serialVersionUID; } public String insert(){ user.setUserNo(user.getUserNo()); user.setDepartmentNo(user.getDepartmentNo()); user.setUserName(user.getUserName()); user.setPassword(user.getPassword()); user.setEmail(user.getEmail()); System.out.println(user.getUserName()+" insert"); this.userservice.insert(user); return SUCCESS; } }

dao接口
UserDao.java

@Repository @Transactional public interface UserDao { public void insert(User user); }

UserMappers.xml

<?xml version="1.0" encoding="UTF⑻"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis⑶-mapper.dtd"> <mapper namespace="gyt.frame.first.UserDao"> <insert id="insert"> insert into User (UserNo,DepartmentNo,UserName,Password,Email) values( #{UserNo,jdbcType=VARCHAR}, #{DepartmentNo,jdbcType=VARCHAR}, #{UserName,jdbcType=NUMERIC}, #{Password,jdbcType=VARCHAR}, #{Email,jdbcType=VARCHAR}) </insert> </mapper>

这里注意namespace不要写错,id为类里面的某个方法。不然会报错。

service接口UserService.java

public interface UserService { public void insert(User user); }

service实现类

/* Bean注解管理 Spring自动扫描管理Bean注解有4种配置模式,以下 @Service 用于业务层(service) 示例:@Service("baseService") @Controller 用于控制层(action) 示例:@Controller("baseAction") @Repository 用于数据访问层(dao) 示例:@Repository("baseDao") @Component 泛型配置(当组件不肯定时用),以上3种配置是基于此扩大 */ /* @Service自动装配到Spring的容器,为其他组件提供服务; 通过@Transactional进行事务的管理; 通过@Resource注入UserDao对象。 */ @Service @Transactional public class UserServiceImpl implements UserService{ @Autowired private UserDao userdao; public void insert(User user) { this.userdao.insert(user); } }

user.jsp

<body> <!-- <form action="user/UserAction!insert.action"> 编号:<input name="UserNo"><br> 部门编号:<input name="DepartmentNo"><br> 姓名:<input name="UserName"><br> 密码:<input name="Password"><br> 邮箱:<input name="Email"><br> <input type="submit" value="肯定"> </form>--> <form action="user/UserAction!insert.action"> 编号:<input name="user.UserNo"><br> 部门编号:<input name="user.DepartmentNo"><br> 姓名:<input name="user.UserName"><br> 密码:<input name="user.Password"><br> 邮箱:<input name="user.Email"><br> <input type="submit" value="肯定"> </form> </body>
