spring ioc xml配置

一个完整的spring xml配置:是把action,service,dao以及其它的资源性配置(如basedao)和公共性配置(如连接数据库)配置在resource.xml中,这样就有四个xml配置信息.

案例:

四个xml配置:

applicationContext-action.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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd" >
　　<bean id="userAction" class="com.cdsxt.action.UserAction" scope="prototype" >
　　　　<property name="userService" ref="userService" />
　　</bean>
</beans>

applicationContext-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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd" >
　　<bean id="userService" class="com.cdsxt.service.impl.UserServiceImpl">
　　　　<property name="userDao" ref="userDao" />
　　</bean>
</beans>

applicationContext-dao.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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd" >
　　<bean id="userDao" class="com.cdsxt.dao.impl.UserDaoImpl" parent="baseDao" ></bean>
</beans>

applicationContext-resource.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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd" >
　　<bean id="baseDao" class="com.base.impl.BaseDaoImpl" lazy-init="true" ></bean>
</beans>

Base:

public interface BaseDao<T> {

}

public class BaseDaoImpl<T> implements BaseDao<T> {
　　private Class clazz;
　　public BaseDaoImpl() {
　　　　ParameterizedType type=(ParameterizedType) this.getClass().getGenericSuperclass();
　　　　clazz = (Class) type.getActualTypeArguments()[0];
　　}
　　public Class getClazz() {
　　　　return clazz;
　　}
　　public void setClazz(Class clazz) {
　　　　this.clazz = clazz;
　　}
}

Action:

public class UserAction {
　　private UserService userService;
　　public void add(){
　　　　System.out.println("=====UserAction=======");
　　　　userService.add();
　　}
　　public UserService getUserService() {
　　　　return userService;
　　}
　　public void setUserService(UserService userService) {
　　　　this.userService = userService;
　　}
　　public static void main(String[] args) {
　　　　String[] rs= new String[]{"applicationContext-action.xml","applicationContext-service.xml","applicationContext-dao.xml","applicationContext-　　resource.xml"};
　　ApplicationContext context = new ClassPathXmlApplicationContext(rs);
　　UserAction u1 = (UserAction) context.getBean("userAction");
　　u1.add();
　　}
}

Service:

public interface UserService {
　　public void add();
}

public class UserServiceImpl implements UserService {
　　private UserDao userDao;
　　@Override
　　public void add() {
　　　　System.out.println("--------UserServiceImpl----------");
　　　　userDao.add();
　　}
　　public UserDao getUserDao() {
　　　　return userDao;
　　}
　　public void setUserDao(UserDao userDao) {
　　　　this.userDao = userDao;
　　}
}

Dao:

public interface UserDao extends BaseDao<User>{
　　public void add();
}

public class UserDaoImpl extends BaseDaoImpl<User> implements UserDao{
　　@Override
　　public void add() {
　　　　System.out.println("=========UserDaoImpl========");
　　}
}

po:

public class User {

}
