Spring 依赖配置

使用方法1：

  //在执行此实例化的时候就会完成所有注入  ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");  UserService service = (UserService)ctx.getBean("userService");

使用方法2：

public class SocketRequest {

/**
* 默认实例
*/
private static final SocketRequest INSTANCE = new SocketRequest();

/**
* 获取默认实例
*
* @return 默认实例
*/
public static SocketRequest get() {
return INSTANCE;
}

/**
* 处理系统控制器操作方法
*
* @param context
* spring上下文
*/
public void methodHolder(ApplicationContext context) {
String[] beans = context.getBeanDefinitionNames();//通过此方法可以获得所有的注入类

}
}

public class GameServer implements ApplicationContextAware{    @Override    public void setApplicationContext(ApplicationContext arg0)            throws BeansException {        SocketRequest.get().methodHolder(arg0);            }}

public class mainServer {    public static void main(String[] args) {//在执行此实例化的时候就会完成所有注入，同时会调用GameServer的setApplicationContext方法

GameServer server = new ClassPathXmlApplicationContext("server.xml").getBean(GameServer.class);

} }

Spring配置

1.属性中引用另外的bean

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">    <!-- IoC控制反转 -->  <bean id="u" class="com.bjsxt.dao.impl.UserDAOImpl">  </bean>  <!-- 属性中引用另外的bean-->      <bean id="userService" class="com.bjsxt.service.UserService">      <property name="userDAO" ref="u" />  </bean></beans>

2.有构造函数的注入

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">    <!-- IoC控制反转 -->    <bean id="u" class="com.bjsxt.dao.impl.UserDAOImpl">    </bean>    <bean id="userService" class="com.bjsxt.service.UserService">    <!-- 有构造函数的注入 -->        <constructor-arg>            <ref bean="u" />        </constructor-arg>    </bean></beans>

3.有属性的注入,直接把属性写入，很少用到

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">    <!-- IoC控制反转 -->    <bean name="u" class="com.bjsxt.dao.impl.UserDAOImpl">        <!-- 有属性的注入,直接把属性写入，很少用到 -->        <property name="daoId" value="123"></property>        <property name="daoStatus" value="DDD"></property>    </bean>    <!-- 可以写id也可以写name(如果是name则可以写特殊字符) -->    <bean id="userService" class="com.bjsxt.service.UserService">        <constructor-arg>            <ref bean="u" />        </constructor-arg>    </bean></beans>

4.scope范围，默认是singleton即单例，如果是prototype则每次是新实例

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">    <!-- IoC控制反转 -->    <bean name="u" class="com.bjsxt.dao.impl.UserDAOImpl">        <property name="daoId" value="123"></property>        <property name="daoStatus" value="DDD"></property>    </bean>    <!-- scope范围，默认是singleton即单例，如果是prototype则每次是新实例 -->    <bean id="userService" class="com.bjsxt.service.UserService" scope="prototype">        <constructor-arg>            <ref bean="u" />        </constructor-arg>    </bean></beans>

5.可以注入集合类型

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">    <!-- IoC控制反转 -->    <bean name="u" class="com.bjsxt.dao.impl.UserDAOImpl">    <!-- 可以注入集合类型 -->        <property name="sets">            <set>                <value>1</value>                <value>2</value>            </set>        </property>        <property name="lists">            <list>                <value>1</value>                <value>2</value>                <value>3</value>            </list>        </property>        <property name="maps">            <map>                <entry key="1" value="1"></entry>                <entry key="2" value="2"></entry>                <entry key="3" value="3"></entry>                <entry key="4" value="4"></entry>            </map>        </property>    </bean>    <bean id="userService" class="com.bjsxt.service.UserService"        scope="prototype">        <constructor-arg>            <ref bean="u" />        </constructor-arg>    </bean></beans>

6.自动装配

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">    <!-- IoC控制反转 -->    <bean name="userDAO" class="com.bjsxt.dao.impl.UserDAOImpl">        <property name="name" value="myname"></property>    </bean>    <!-- 自动装配(用的不多)：           byName按名称自动匹配（即要装配的bean中的属性名称和配置中的bean名称相同就会自动装配，如UserService类中的属性和userDAO的bean名称相同就自动装配）           byType按类型自动匹配 （即要装配的bean中的属性类型和配置中的bean的类型相同就会自动装配，如UserService类中的属性类型和userDAO的bean类型相同就自动装配）    -->    <bean id="userService" class="com.bjsxt.service.UserService"        autowire="default">    </bean></beans>

7.初始化bean时执行init-method方法和销毁的时候执行destroy-method方法

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"           default-autowire="byName" >    <!-- IoC控制反转 -->    <bean name="userDAO" class="com.bjsxt.dao.impl.UserDAOImpl">        <property name="name" value="myname"></property>    </bean>    <!-- 初始化bean时执行init-method方法和销毁的时候执行destroy-method方法 -->    <bean id="userService" class="com.bjsxt.service.UserService"        init-method="init" destroy-method="destroy">    </bean></beans>

8.使用注解

<?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-2.5.xsd            http://www.springframework.org/schema/context           http://www.springframework.org/schema/context/spring-context-2.5.xsd">    <context:annotation-config></context:annotation-config></beans>

9.扫描包名，包名下的类都可以注入。

<?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-2.5.xsd            http://www.springframework.org/schema/context           http://www.springframework.org/schema/context/spring-context-2.5.xsd">    <context:component-scan base-package="com.bjsxt"></context:component-scan></beans>

10.实际项目配置参考

<?xml version="1.0" encoding="UTF-8"?><beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jdbc="http://www.eelpo.com/schema/jdbc" xmlns="http://www.springframework.org/schema/beans"
