javaBean代码
package test;
public class Person {
private String name;
private int age;
public Person(){}
public Person(String name,int age){
this.name=name;
this.age=age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
运行后结果：
要么就是找不到类，要么就是属性值找不到。求大神指教
