JSP Spring配置文件中传值的实例详解

public class Test1 {    private String name = "nihao";    public String getName() {     return name;   }  } 

<bean id="t1" class="i.test.Test1" />  <!-- name = t1.getName() --> <bean id="name"   class="org.springframework.beans.factory.config.PropertyPathFactoryBean"   p:targetObject-ref="t1" p:propertyPath="name" /> 

public class Test3 {    private Test1 t1 = new Test1();   private String name;    public void setName(String name) {     this.name = name;   }    public Test1 getT1() {     return t1;   }  }  

<!-- 将t1的name属性值赋给t3的name --> <bean id="t3" class="i.test.Test3">   <property name="name">     <!-- 执行t3.getT1().getName() -->     <bean id="t3.t1.name"       class="org.springframework.beans.factory.config.PropertyPathFactoryBean" />    </property> </bean>  

public class Test3 {   public String name = "nihao";   public static final int MAX_LENGTH = 10; }

<!-- 访问静态field只需要类路径 --> <bean id="length"   class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean"   p:targetClass="i.test.Test3" p:targetField="MAX_LENGTH" />  <!-- 或者 --> <bean id="length"   class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean"   p:staticField="i.test.Test3.MAX_LENGTH" />  

public class Test3 {   public void execute(String str, int i) {     System.err.println(str + "--" + i);   } } 

<bean id="t3" class="i.test.Test3" />  <bean   class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"   p:targetObject-ref="t3" p:targetMethod="execute">   <property name="arguments">     <list>       <value>nihao</value>       <value>56</value>     </list>   </property> </bean>
