package action.convert;

public class User {

private String name;
private int age;
private double score;
private Date birthday;

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;
}

public double getscore() {
return score;
}

public void setscore(double score) {
this.score = score;
}

public Date getBirthday() {
return birthday;
}

public void setBirthday(Date birthday) {
this.birthday = birthday;
}

@Override
public String toString() {
return "User{" +
"name='" + name + '\'' +
", age=" + age +
", score=" + score +
", birthday=" + birthday +
'}';
}
}

异常原因

因为User的score属性的set,get防范书写不规范, 所以导致获取不到值, 将方法名改为 setScoregetScore 即可
