Ⅴ.spring的点点滴滴--引用其他对象或类型的成员

承接上文

引用其他对象或类型的成员

.net篇（环境为vs2012+Spring.Core.dll v1.31）

public class Person {
    public string Name { get; set; }
    public static int Age { get; set; }
    public string sex;
    public static int Add(int x, int y){
        return x + y;
    }
    public int Add(int x, int y,int z){
        return x + y+z;
    }
}
   <object id="person" type="SpringBase.Person,SpringBase">
    <property name="Name" value="cnljli" />
    <property name="Age" value="1"/>
    <property name="sex" value="0"/>
  </object>
  <object id="theName"
        type="Spring.Objects.Factory.Config.PropertyRetrievingFactoryObject, Spring.Core">
    <property name="TargetObject" ref="person"/>
    <property name="TargetProperty" value="Name"/>
  </object>
  <object id="theAge"
        type="Spring.Objects.Factory.Config.PropertyRetrievingFactoryObject, Spring.Core">
    <property name="StaticProperty" value="SpringBase.Person.Age"/>
  </object>
  <object id="thesex"
     type="Spring.Objects.Factory.Config.FieldRetrievingFactoryObject, Spring.Core">
    <property name="TargetObject" ref="person"/>
    <property name="TargetField" value="sex"/>
  </object>
  <object id="theadd1"
    type="Spring.Objects.Factory.Config.MethodInvokingFactoryObject, Spring.Core">
    <property name="TargetType"  value="SpringBase.Person,SpringBase"/>
    <property name="TargetMethod" value="Add"/>
    <property name="Arguments">
      <list>
        <value>1</value>
        <value>2</value>
      </list>
    </property>
  </object>
  <object id="theadd2"
    type="Spring.Objects.Factory.Config.MethodInvokingFactoryObject, Spring.Core">
    <property name="TargetObject"  ref="person"/>
    <property name="TargetMethod" value="Add"/>
    <property name="NamedArguments">
      <dictionary>
        <entry key="x" value="1" />
        <entry key="y" value="2" />
        <entry key="z" value="3" />
      </dictionary>
    </property>
  </object>
  1. StaticProperty的值必须填完整
  2. Arguments的值的时候是从上往下匹配,NamedArguments是通过键值对匹配

java篇（环境为Maven+Jdk1.7+IntelliJ IDEA 12.1.4）

package springdemo;
public class factoryObject {
    private String name;
    public static Integer age;
    public String sex;
    public static int Add(int x, int y) {
        return x + y;
    }
    public static Integer getAge() {
        return age;
    }
    public static void setAge(Integer age) {
        factoryObject.age = age;
    }
    public int Add(int x, int y, int z) {
        return x + y + z;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
}
    <bean id="person" class="springdemo.factoryObject">
        <property name="name" value="cnljli"/>
        <property name="age" value="1"/>
        <property name="sex" value="0"/>
    </bean>
    <bean id="theName"
          class="org.springframework.beans.factory.config.PropertyPathFactoryBean">
        <property name="targetBeanName" value="person"/>
        <property name="propertyPath" value="name"/>
    </bean>
    <bean id="theAge"
          class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean">
        <property name="staticField" value="springdemo.factoryObject.age"/>
    </bean>
    <bean id="thesex"
          class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean">
        <property name="TargetObject" ref="person"/>
        <property name="targetField" value="sex"/>
    </bean>
    <bean id="theadd1"
          class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
        <property name="targetClass" value="springdemo.factoryObject"/>
        <property name="targetMethod" value="Add"/>
        <property name="arguments">
            <list>
                <value>1</value>
                <value>2</value>
            </list>
        </property>
    </bean>
    <bean id="theadd2"
          class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
        <property name="targetObject" ref="person"/>
        <property name="targetMethod" value="Add"/>
        <property name="arguments">
            <list>
                <value>1</value>
                <value>2</value>
                <value>3</value>
            </list>
        </property>
    </bean>
  1. 字段必须有get和set的方法

java和Csharp的共同点

  1. theadd1是静态方法,theadd2为实例方法
  2. 就是标签的name几乎一样
  3. 分别的效果是获取属性、静态字段(csharp为静态属性)、获取字段、静态方法返回、实例方法返回
