当我在控制台中运行应用程序时，结果是正确的。父正在更新，孩子不能删除。
app.java
public class app {
public static void main(String[] args) {
GenericXmlApplicationContext ctx = new GenericXmlApplicationContext();
ctx.load("classpath:app-context-annotation.xml");
ctx.refresh();
ClientService clientService = ctx.getBean("jpaClientService", ClientService.class);
UserService userService = ctx.getBean("jpaUserService", UserService.class);
CustomerService customerService = ctx.getBean("jpaCustomerService", CustomerService.class);
TroubleService troubleService = ctx.getBean("jpaTroubleService", TroubleService.class);
Client newClient = clientService.findOne(8l);
String newClientName = "IP 8";
newClient.setClient(newClientName);
clientService.saveClient(newClient);
clientList("Find all:", clientService.findAll());
System.out.println(client.getUserList());*/
}
private static void clientList (String message, List<Client> clientList) {
System.out.println(message);
for (Client client : clientList) {
System.out.println(client);
}
}
private static void userList (String message, List<User> userList) {
System.out.println(message);
for (User user : userList) {
System.out.println(user);
}
}
private static void troubleList (String message, List<Trouble> troubleList) {
System.out.println(message);
for (Trouble trouble : troubleList) {
System.out.println(trouble);
}
}
}
但是，当我使用MVC时，当父级更新时，所有子级都被从所有表中删除。

我做错了什么？ app-context == webapp-context
答案 0 :(得分：0)
解决。已删除＆＃34; orphanremoval = true＆＃34;来自实体。
