Question

我有一个@Service bean，其功能是将新的Member实体保存到数据库：

@Service
public class AccountService {
    // method A
    public void saveMember(Member m) {
        entityManager.persit(m);
    }

    // method B
    public void saveMember(String username, String pwd, int age /* ... lots of parameters ... */) {
        Member m = new Member();
        m.setUsername(username);
        m.setPassword(pwd);
        // ... ...

        entityManager.persit(m);
    }
}

我将直接在saveMember() bean中调用@Controller。哪种方法更好？如果我使用方法A，那么我必须在Member bean中构造@Controller实体，如下所示：

@Controller
public class Controller {

    public String profile(@RequestParam String username,
                        @RequestParam String password
                        // ... ...
                        ) {
        Member m = new Member();
        m.setXXX();
        // ... ...
        // lots of setters method invocation
        accountService.saveMember(m);
    }
}

如果使用方法B：

@Controller
public class Controller {

    public String profile(@RequestParam String username,
                        @RequestParam String password
                        // ... ...
                        ) {
        accountService.saveMember(username, password /* lots of parameters */);
    }
}

哪个更好？谢谢！

有第三种方法

在您的控制器中，您将获得Member对象作为输入，您可以使用此对象来调用您服务中的方法。

@RequestMapping(value = "/saveMember", method = RequestMethod.POST)
@ResponseBody
public String saveAddress(@RequestBody Member member) {
    accountService.saveMember(member);
    ....
}

以下是进行调用的javascript代码：

saveMember = function() {
    var saveURL = '/saveMember';

    var memberData = {};
    memberData.username = 'some user name';
    memberData.password = 'some password';
    .... (your other fields)

    $.ajax({
        url : saveURL,
        method : 'POST',
        dataType : 'json',
        contentType : 'application/json',
        data : JSON.stringify(memberData),
        success : function(result) {
            ...
        }, error: function(errorObject) {
            console.log(errorObject);
        }
    });
};

我应该在Controller中构建实体Bean吗？
