Question

我无法通过roo为一对多关系生成适当的GUI。特别是，我需要一个多选元素来在权限（spring security）中进行选择以与用户相关联。

我创建了我的RegisteredUser类：

@RooJavaBean
@RooToString
@RooJpaActiveRecord
public class RegisteredUser extends MyUser implements UserDetails,
    CredentialsContainer {

private String password;
private String username;
private Boolean enabled = true;
private Boolean accountNonExpired = true;
private Boolean credentialsNonExpired = true;
private Boolean accountNonLocked = true;

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Set<MyBaseAuthority> authorities = new HashSet<MyBaseAuthority>();

@Override
public void eraseCredentials() {
    password = null;
}

@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
    return authorities;
}

@Override
public String getPassword() {
    return password;
}

@Override
public String getUsername() {
    return username;
}

@Override
public boolean isAccountNonExpired() {
    return accountNonExpired;
}

@Override
public boolean isAccountNonLocked() {
    return accountNonLocked;
}

@Override
public boolean isCredentialsNonExpired() {
    return credentialsNonExpired;
}

@Override
public boolean isEnabled() {
    return enabled;
}
}

然后是MyBaseAuthority类：

@RooJavaBean
@RooToString
@RooJpaActiveRecord
public class MyBaseAuthority extends ObjectWithId implements
    GrantedAuthority {
   private String authority;

@Override
public String getAuthority() {
    return authority;
}
}

然后我不得不手动为MyBaseAuthority创建控制器，但不是为RegisteredUser（由webmvc命令生成）创建控制器：

@RequestMapping("/registeredusers")
@Controller
@RooWebScaffold(path = "registeredusers", formBackingObject = RegisteredUser.class)
public class RegisteredUserController {
}

@RequestMapping("/authorities")
@Controller
@RooWebScaffold(path = "authorities", formBackingObject = MyBaseAuthority.class)
public class MyBaseAuthorityController {
}

在GUI上，我可以创建并列出所有权限和注册用户。但是，在创建注册用户时，我只能设置字符串字段和布尔字段，而不能设置一对多关系。我该如何解决这个问题？

Answer 1

如果我试图完成这项任务，我会打印出所有复选框，并将可用选项打印为数组键，其名称如下：

<input type="checkbox" name="role[]" value="ROLE_ONE">
<input type="checkbox" name="role[]" value="ROLE_TWO">

然后，我将这些参数映射到String []数组，如this post

@RequestParam(value="myParam[]" String roles)

然后我会循环遍历字符串并添加创建MyBaseAuthority对象，附加您的用户并持久化（）它们。
