I have tried multiple versions and read several related answers, but I still cant figure out why Struts is not populating my Action property user
.
我已经尝试了多个版本并阅读了几个相关的答案,但我仍然无法弄清楚为什么Struts没有填充我的Action属性用户。
This is my ajax call
这是我的ajax电话
function save_new_user() {
var user =
{ username: $('#new_user_username').val(),
email: $('#new_user_email').val(),
password: $('#new_user_password').val()
};
user_json = JSON.stringify(user);
console.log(user_json);
var data = {'user': user_json};
$.ajax({
type : 'GET',
url : 'SaveNewUser',
data: data,
dataType : "json",
contentType: 'application/json',
success : function(data, textStatus, jqXHR) {
if(data) {
}
},
});
}
which, by the way, print this in the console
顺便说一下,在控制台中打印它
{"username":"dd","email":"ff","password":"gg"}
My Action class (with annotations), (I am not modifying the json-default
interceptor from struts2-json-plugin-2.3.24.1) is
我的Action类(带注释),(我没有修改struts2-json-plugin-2.3.24.1中的json-default拦截器)
package coproject.cpweb.actions;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;
import com.opensymphony.xwork2.ActionSupport;
import coproject.cpweb.utils.db.entities.UserDum;
import coproject.cpweb.utils.db.services.DbServicesImp;
@Action("SaveNewUser")
@ParentPackage("json-default")
@Results({
@Result(name="success", type="json"),
@Result(name="input", location="/views/error.jsp")
})
public class SaveNewUser extends ActionSupport{
private static final long serialVersionUID = 1L;
/* Services */
DbServicesImp dbServices;
public DbServicesImp getDbServices() {
return dbServices;
}
public void setDbServices(DbServicesImp dbServices) {
this.dbServices = dbServices;
}
/* Input Json */
private UserDum user = new UserDum();
public UserDum getUser() {
return user;
}
public void setUser(UserDum user) {
this.user = user;
}
/* Execute */
public String execute() throws Exception {
// dbServices.saveUser(user);
System.out.println(user.getUsername());
return "SUCCESS";
}
}
And the UserDum
entity is
而UserDum实体是
package coproject.cpweb.utils.db.entities;
public class UserDum {
private String username;
private String email;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
However, when the request arrives, the json
interceptor of struts-json-plugin gets an exception trying to set "user".
但是,当请求到达时,struts-json-plugin的json拦截器会尝试设置“user”。

Extending json-default
package doesn't set json
interceptor to the defaultStack
of interceptors, it just defines that there is such interceptor.
扩展json-default包不会将json拦截器设置为defaultStack的拦截器,它只是定义了这样的拦截器。
Use interceptorRefs
in your @Action
annotation to set json
interceptor and the defaultStack
to the action.
在@Action注释中使用interceptorRefs将json拦截器和defaultStack设置为action。
@Action(value="SaveNewUser",
interceptorRefs={ @InterceptorRef("json"),
@InterceptorRef("defaultStack") })
Or @InterceptorRefs
at the class level to apply interceptors to all actions defined in that class.
或类级别的@InterceptorRefs将拦截器应用于该类中定义的所有操作。
@InterceptorRefs({
@InterceptorRef("json"),
@InterceptorRef("defaultStack")
})
