SSM框架是由SpringMVC、Spring、MyBatis框架整合而成.
maven
pom.xml配置

SpringMVC:
web.xml配置文件
<!--配置springMVC--> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--解决配置文件--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring/springMVC-*.xml</param-value> </init-param> <!--早点被加载--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping>
SpringMVC-servlet.xml配置
<?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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--扫描带@Control的类--> <context:component-scan base-package="com.zr.actions"/></beans>
Spring配置
web.xml配置
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring/applicationContext.xml</param-value> </context-param> <!--spring--> <!--监听在容器启动的时候被调用,容器关闭的时候消失spring的配置监听器监听对象HttpServletRequest、HttpSession、ServletContext--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
applicationContext.xml配置
<?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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:component-scan base-package="com.zr"> <!--regex:正则表达式 扫描不包含actions包--> <context:exclude-filter type="regex" expression="com.zr.actions"/> </context:component-scan></beans>
MyBatis配置
applicationContext.xml配置
<!--数据源--> <bean id="dataSource" class="org.apache.ibatis.datasource.pooled.PooledDataSource"> <property name="username" value = "spring"></property> <property name="password" value="root"></property> <property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"></property> <property name="driver" value="oracle.jdbc.OracleDriver"></property> <property name="poolMaximumActiveConnections" value="20"></property> <!--最大等待时间--> <property name="poolTimeToWait" value="2000"></property> </bean> <bean id="sqlSessionFactory" class = "org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="typeAliasesPackage" value="com.zr.entity"></property> <!--mapper文件和Mapper.xml不在同一路径下需要--> <property name="mapperLocations" value="classpath:mybatis/*.Mapper.xml"></property> </bean> <!--将接口和mapper.xml对应起来,自动注入--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> <property name="basePackage" value="com.zr.mapper"></property> </bean>
接口及相关类的配置
user类
//别名@Alias("user")public class User { private Integer id; private String userName; private String passWord; public Integer getId() { return id;
} public void setId(Integer id) { this.id = id;
} 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;
} @Override
public String toString() { return "User{" + "id=" + id + ", userName='" + userName + '\'' + ", passWord='" + passWord + '\'' + '}';
}
}IUserMapper接口
public interface IUserMapper { User findByUserAndPass(
@Param("userName") String userName,
@Param("passWord") String passWord);
}IUserService接口
public interface IUserService { boolean loginCheck(String userName,String passWord);
}UserServiceImpl类(service的实现类)
@Service("ius")public class UserServiceImpl implements IUserService { @Resource
private IUserMapper iUserMapper; @Override
public boolean loginCheck(String userName, String passWord) {
User user = iUserMapper.findByUserAndPass(userName,passWord); if(user==null){ return false;
}else{ return true;
}
}
}
