nice 不错哦
关于BigDecimal.ROUND_HALF_UP与ROUND_HALF_DOWN
有两种用法,一种是直接吧方法的返回值注入到实例的属性,二是用返回值定义成Bean
定义实体:
public class Person ...{
private Son son;
private String age;
public String getAge() ...{
return age;
}
public void setAge(String age) ...{
this.age = age;
}
public Son getSon() ...{
return son;
}
public void setSon(Son son) ...{
this.son = son;
}
}
package Bean.superIOCmethod;
public class Son ...{
private String age;
public String getAge() ...{
return age;
}
public void setAge(String age) ...{
this.age = age;
}
}
public static final String TEST_FIELD="welcom";
public String getValue(){
return "test";
}
public static String getStaticValue(){
return "static test";
}
}
配置文件:
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- 非静态方法,使用targetObject -->
<bean id="son" class="Bean.superIOCmethod.Son">
<property name="age">
<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject">
<ref local="value"/>
</property>
<property name="targetMethod">
<value>getValue</value>
</property>
</bean>
</property>
</bean>
<!-- 静态方法,无需使用targetObject,但要配置targetClass -->
<bean id="staticson" class="Bean.superIOCmethod.Son">
<property name="age">
<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetClass">
<value>Bean.superIOCmethod.Field</value>
</property>
<property name="targetMethod">
<value>getStaticValue</value>
</property>
</bean>
</property>
</bean>
<!-- 将方法返回值定义成Bean -->
<bean id="sysProps" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetClass">
<value>java.lang.System</value>
</property>
<property name="targetMethod">
<value>getProperties</value>
</property>
</bean>
<bean id="javaversion" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject">
<ref local="sysProps"/>
</property>
<property name="targetMethod">
<value>getProperty</value>
</property>
<property name="arguments">
<list>
<value>java.version</value>
</list>
</property>
</bean>
<bean id="value" class="Bean.superIOCmethod.Field">
</bean>
</beans>
测试代码:
String path=new Test().getClass().getResource("/").getPath();
String realpath=path.substring(1, path.length());
ApplicationContext context=new FileSystemXmlApplicationContext(realpath+"/superIOCmethod.xml");
Son son1=(Son)context.getBean("son");
Son son2=(Son)context.getBean("staticson");
System.out.println("person age is:"+son1.getAge());
System.out.println("person age is:"+son2.getAge());
System.out.println(context.getBean("sysProps"));
System.out.println(context.getBean("javaversion"));
}
person age is:test
person age is:static test
