Question

这是我的实体

 @Entity
 public class User  implements java.io.Serializable {

 @Id
 @GeneratedValue(strategy = GenerationType.AUTO)
 private int id;


 private String name;

 private String mobNum;

 private String email;



 String gender;


  @Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
  LocalDate bdate;

public LocalDate getDate() {
    return bdate;
}

public void setDate(LocalDate bdate) {
    this.bdate = bdate;
}



public String getGender() {
    return gender;
}

public void setGender(String gender) {
    this.gender = gender;
}



public User() {

}


public String getName() {
    return this.name;
}

public void setName(String name) {
    this.name = name;
}


public String getMobNum() {
    return this.mobNum;
}

public void setMobNum(String mobNum) {
    this.mobNum = mobNum;
}


public String getEmail() {
    return this.email;
}

public void setEmail(String email) {
    this.email = email;
}

}

这是我的Spring-Form

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<body>
    <form:form action="add_student_data.htm" method="POST" commandName="user">
     <table>



          <tr>
          <td><form:label path="name">Name</form:label></td>
          <td><form:input path="name"/></td>
          <td><font color="red" /><form:errors path="name" cssClass="error" /></td>
        </tr>



          <tr>
          <td><form:label path="bdate" >Date Of Birth</form:label></td>
          <td><form:input path="bdate"/></td>
          <td><font color="red" /><form:errors path="bdate" cssClass="bdate" /></td>
            </tr>

             <tr>
          <td><form:label path="gender" >Gender</form:label></td>
          <td><form:radiobutton path="gender" value="M" label="M" />
          <form:radiobutton path="gender" value="F" label="F" /></td>

            </tr>

            <tr>
            <td><form:label path="mobNum">Mob Num</form:label></td>
            <td><form:input path="mobNum"/></td>
            <td><font color="red" /><form:errors path="mobNum" ccssClass="error"/></td>
              </tr>

              <tr>
              <td><form:label path="email">Email</form:label></td>
                <td><form:input path="email"/></td>
                <td><font color="red" /><form:errors path="email" cssClass="error" /></td>
                  </tr>
        </table>     
                <input type="submit" value="submit">

     </form:form>
   </body>
</html>

当我想打开这个fom错误时，就像

一样

＆＃34; org.apache.jasper.JasperException：org.springframework.beans.NotReadablePropertyException：无效的属性＆＃39; dateOfBirth＆＃39; bean类[com.domain.User]：Bean属性＆＃39; dateOfBirth＆＃39;不可读或getter方法无效：getter的返回类型是否与setter的参数类型匹配？＆＃34;

我在用户实体中使用joda.org.time.LocalDate。问题的原因是什么？

Answer 1

JSP中的getter / setter方法名称和变量名称不匹配，请更改以下方法：

public LocalDate getDate() {
    return bdate;
}

public void setDate(LocalDate bdate) {
    this.bdate = bdate;
}

到

public LocalDate getBdate() {
    return bdate;
}

public void setBdate(LocalDate bdate) {
    this.bdate = bdate;
}

Spring形式的LocalDate
