利用java的反射机制，比较两个实体类的属性值是否相等，字符串支持正则表达式匹配，同时支持只对两个实体类的字符类型进行比较。

Compare two java beans with java Reflection.

Features

• 比较两个实体类的属性值是否相等

• 支持正则比较两个字符串

• 支持只比较字符串

• Compare two java beans

• Support regular string comparison

• Support only compare string in two beans.

Demo

public class Run {
    public static void main(String[] args) throws Exception {
		Cmp2beans cmp2beans=new Cmp2beans();
		Host whiteHost=new Host();
		Host blackHost=new Host();
		
		List whiteDogs=new ArrayList();
		List blackDogs=new ArrayList();
		whiteDogs.add(new Dog("jia",10.5));
		blackDogs.add(new Dog("ji[\\s\\S]*", 10.5));
		
		whiteHost.setAge(30);
		whiteHost.setCat(new Cat("tom", 3));
		whiteHost.setDogs(whiteDogs);
		blackHost.setAge(30);
		blackHost.setCat(new Cat("tom", 2));
		blackHost.setDogs(blackDogs);
		
		cmp2beans.compare(whiteHost, blackHost, true, false);
		
	}
}

结果(result):Exception in thread "main" java.lang.Exception: Class[Cat] Attributes[age] Mismatch;source[3],target[2]
