struts 2 获取不到后台数据库的值

想要在前台显示存入数据库的个人信息，people属性有name,age,sex,education
sex和education单独设置了java bean
前台jsp页面：
<s:iterator value="peoplelist" var="p">
<s:property value="#p.name"/> |
<s:property value="#p.age"/> |
<s:property value="#p.sex.value"/>|
<s:property value="#p.education.value"/>|

<a href="/T_Manager/People_delete?id=<s:property value="#p.id"/>">删除people</a> |
<a href="/T_Manager/People_updateInput?id=<s:property value="#p.id"/>">更新people</a>
<br/>
</s:iterator>

java bean：

public class Education {
private String Key;
private String value;

public String getKey() {
return Key;
}
public void setKey(String key) {
Key = key;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public Education(){}
public Education(String key, String value) {
super();
Key = key;
this.value = value;
}
}

public class EducationService {
public Education[] getEducation(){
return new Education[]{
new Education("1","小学"),
new Education("2","中学"),
new Education("3","高中"),
new Education("4","大学"),
new Education("5","研究生"),
new Education("5","硕士"),
new Education("5","博士")
};
}
}

可是，前台获取不到sex和education的信息。。哪里有问题？

Answer 1

你没有将education对象赋予到peoplelist中的education属性吧、

Answer 2

你的peoplelist哪里来的？
