這是我的控制器類如何將列表數據thymeleaf html綁定到spring控制器？
package com.myblog.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;
import com.myblog.model.User;
@Controller
public class UserController {
private static final Logger log = LoggerFactory.getLogger(UserController.class);
@GetMapping(value="/user")
public String getUser(Model model){
model.addAttribute("user", new User());
return "user";
}
@PostMapping(value="/user")
public String postUser(@ModelAttribute("user") User user){
log.info("user :"+user);
return "user";
}
}
這是我的模型類 user.java
package com.myblog.model;
import java.util.ArrayList;
import java.util.List;
public class User {
private int id;
private String name;
private List<Address> address=new ArrayList<Address>();
@Override
public String toString() {
return "User [name=" + name + ", address=" + address + "]";
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<Address> getAddress() {
return address;
}
public void setAddress(List<Address> address) {
this.address = address;
}
}
address.java
package com.myblog.model;
public class Address {
private int id;
private String street;
private String city;
public int getAddid() {
return addid;
}
public void setAddid(int addid) {
this.addid = addid;
}
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
}
這是我thymeleaf HTML頁面

控制器用戶對象不會將數據綁定到地址模型對象中。 輸出爲user：user [name =「name」，address []]
我嘗試 '日：場= 「* {} user.address.city」' 這是不工作 –
謝謝ANSGAR日：場= 「地址[0] .street」 工作 –
我不t完全知道thymleaf的語法，但你應該可以像'th：each =「anAddress：* {address}'做一些事情，然後在循環中使用'th：field =」$ {anAddress.street}「'例如，但我不完全確定。 –
