Mule的第一個應用非常簡單。卻也可以看出Mule的運行機制。上例中，實現的是Hello world 的例子，過程為：用戶輸入內容，回車，然后顯示Hello，[輸入的內容]。這個實現非常簡單，但是，卻也存在一些問題，mule是怎么知道顯示這些內容的，現在就研究這個。

也許大家覺得，在XXXX.xml中已經配置了類路徑，mule當然可以找到這個類，問題就在這里，mule找到了實現類，那他是如何找到對應的方法的呢？OK，做一下嘗試

1、嘗試一

將inteface修改為：

[java] view plaincopyprint?

package demo.mule.umo;?

?

public interface HelloWorld {?

??? public String sayHello(String str);?

??? public String sayHello();?

}?

package demo.mule.umo;public interface HelloWorld {public String sayHello(String str);public String sayHello(); }

實現類修改為：

[java] view plaincopyprint?

package demo.mule.umo.impl;?

import demo.mule.umo.HelloWorld;?

public class HelloWorldImpl implements HelloWorld {?

??? @Override?

??? public String sayHello(String str) {?

??????? return "Hello," + str;?

??? }?

??? @Override?

??? public String sayHello() {?

??????? return "Hello world";?

??? }?

}?

package demo.mule.umo.impl; import demo.mule.umo.HelloWorld; public class HelloWorldImpl implements HelloWorld {@Overridepublic String sayHello(String str) {return "Hello," + str;}@Overridepublic String sayHello() {return "Hello world";} }

運行項目：運行成功！

2、嘗試二

修改interface為：

[java] view plaincopyprint?

package demo.mule.umo;?

?

public interface HelloWorld {?

??? public String sayHello(String str);?

??? public String sayHello2(String str);?

}?

package demo.mule.umo;public interface HelloWorld {public String sayHello(String str);public String sayHello2(String str); }

修改實現類為：

[java] view plaincopyprint?

package demo.mule.umo.impl;?

import demo.mule.umo.HelloWorld;?

public class HelloWorldImpl implements HelloWorld {?

??? @Override?

??? public String sayHello(String str) {?

??????? return "Hello," + str;?

??? }?

??? @Override?

??? public String sayHello2(String str) {?

??????? return "Hello2 ," + str;?

??? }?

}?

package demo.mule.umo.impl; import demo.mule.umo.HelloWorld; public class HelloWorldImpl implements HelloWorld {@Overridepublic String sayHello(String str) {return "Hello," + str;}@Overridepublic String sayHello2(String str) {return "Hello2 ," + str;} }

運行：拋出ERROR

[java] view plaincopyprint?

結論：

比較兩次拋出的ERROR，不難發現這句話“

Could not find entry point on: "demo.mule.umo.impl.HelloWorldImpl" with arguments: "{class java.lang.String}" using resolver "ReflectionEntryPointResolver{ignoredMethods=[getClass, clone, equals, hashCode, getInvocationHandler, get*, wait, is*, notify, toString, notifyAll]{transformFirst=true, acceptVoidMethods=false}"

”，真相大白：mule通過<inbound></inbound>中得到的結果，作為尋找方法中參數的依據，由于該項目中，從終端輸入的內容，項目接收時為String類型，因此，mule將查找參數類型為String的方法，同時，mule將拋棄所有符合“getClass, clone, equals, hashCode, getInvocationHandler, get*, wait, is*, notify, toString, notifyAll”的方法，如果符合條件的只有一個，那正好調用，否則，就拋出ERROR。

如果程序中很可以確定是哪個方法，大可讓他自己去找，成人之美，若是不能確定是哪個方法，那么就只能夠指腹為婚了，進行如下配置：

將嘗試二的配置文件修改為：
