SpringBoot将返回参数封装成类

当返回类型为下图，怎么返回：

图片的上部分是三个string类型，从user表中获取。下部分，从organization表中获取。

怎么如下图所示用一个变量email，返回所有信息呢？

可以建一个 Java类：比如起名为OrganizationEmail.java。里面定义我们需要的字段：

@Data
    public class OrganizationEmail {
        private String name;
        private String phone;
        private String email;
    
        private List<Organization> organizations;
        public OrganizationEmail() {
            organizations = new ArrayList<>();
        }
    
    }

在lmpl.java里来将需要的信息赋值给我们上面定义好的OrganizationEmail.java。

//查询user表，获取用户信息
        @Override
        public OrganizationEmail getByUserId(String id) {
            //查询表获取信息
            User userInfo = userMapper.getById(id);
            //获得组织信息
            List<Organization> organizationUsers = organizationUserMapper.selectByUserId(id);
            //将获取信息赋予OrganizationEmail
            OrganizationEmail email = new OrganizationEmail();
            email.setName(userInfo.getName());
            email.setPhone(userInfo.getPhone());
            email.setEmail(userInfo.getEmail());
            email.setOrganizations(organizationUsers);
            return email;
        }

这样email包含所需全部信息。像第二张图片return email即可。
