Spring Propertypathfactorybean | Get a property value for another bean

In general, the dependency in spring comes from another bean, but there are situations where we need a property of another bean, and we can use Propertypathfactorybean.

eg

Continuation of the Dog class:

 PackageFuckspring.propertyeditor; Public classDog {PrivateString name; PrivateString type; Private intAge ;  PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }     PublicString GetType () {returntype; }     Public voidsetType (String type) { This. Type =type; }     Public intGetage () {returnAge ; }     Public voidSetage (intAge ) {         This. Age =Age ; }         PublicString toString () {return  This. name+ This. type+ This. Age; }}

Another person class:

 PackageFuckspring.propertyeditor; Public classPerson {PrivateString name; PrivateString Hisdogname;  PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }     PublicString Gethisdogname () {returnHisdogname; }     Public voidsethisdogname (String hisdogname) { This. Hisdogname =Hisdogname; }    }

And then our test class, Mytest.java.

 PackageFuckspring.propertyeditor;ImportOrg.springframework.context.ApplicationContext;ImportOrg.springframework.context.support.ClassPathXmlApplicationContext; Public classMyTest {PrivatePerson p;  PublicPerson Getp () {returnp; }     Public voidSETP (person p) { This. P =p; }     Public Static voidMain (string[] args) {ApplicationContext ac=NewClasspathxmlapplicationcontext ("Applicationcontext.xml"); MyTest MT= (MyTest) ac.getbean ("MyTest"); String Hisdog=Mt.p.gethisdogname ();            System.out.println (Hisdog); }    }

And finally, our applicationcontext.xml.

<?XML version= "1.0" encoding= "UTF-8"?><!DOCTYPE Beans Public "-//spring//dtd BEAN 2.0//en" "Http://www.springframework.org/dtd/spring-beans-2.0.dtd" [ <!

Then run Mytest.java,,, binggo! success ~
