重定向至@ResponseBody？

发布于 2024-11-07 13:23:53 字数 715 浏览 0 评论 0 原文

我有一些通过 spring security 进行 ajax 登录的方法：

@RequestMapping(value="/entry.html", method=RequestMethod.GET)
public String getEntry(){
    return isAuthenticated()? "redirect:/logout.jsp":"entry";
}

@RequestMapping(value="/postLogout.html", method=RequestMethod.GET)
public @ResponseBody String getPostLogout(){
    return "{success:true, logout:true, session:false}";
}

流程是，当收到对 /entry.html 的调用时，它将检查并选择

重定向到 /logout.jsp =>由 spring security 处理，然后重定向到 /postLogout.html =>响应JSON
解析为查看entry，这是一个仅包含json字符串的jsp

我想知道是否可以在getEntry()@ResponseBody code> 不使用 jsp 只写一个 json 值？

I have something for ajax login through spring security:

@RequestMapping(value="/entry.html", method=RequestMethod.GET)
public String getEntry(){
    return isAuthenticated()? "redirect:/logout.jsp":"entry";
}

@RequestMapping(value="/postLogout.html", method=RequestMethod.GET)
public @ResponseBody String getPostLogout(){
    return "{success:true, logout:true, session:false}";
}

The flow is that when receive a call to /entry.html, it will check and choose to

redirect to /logout.jsp => handled by spring security and then redirect to /postLogout.html => response JSON
resolve to view entry, which is a jsp contain only a json string

I would like to know if I can use @ResponseBody in getEntry() without using an jsp to write just a json value?

从 Spring 返回 JSON 的最简单方法是通过 Jackson。

我将创建一个自定义返回对象：

public class MyReturnObject{
private boolean success;
private boolean session;
private boolean logout;
// + getters and setters
// + 3-arg constructor
}

并编写如下所示的控制器方法：

@RequestMapping(value="/postLogout.html", method=RequestMethod.GET)
@ResponseBody 
public MyreturnObject getPostLogout(){
    return new ReturnObject(true,true,false);
}

Spring + Jackson 将负责将对象序列化为 JSON 并设置正确的 mime 类型。请参阅我之前的回答以获得完整的工作版本。

The easiest way to return JSON from Spring is through Jackson.

I'd create a custom return Object:

public class MyReturnObject{
private boolean success;
private boolean session;
private boolean logout;
// + getters and setters
// + 3-arg constructor
}

and write the controller method like this:

@RequestMapping(value="/postLogout.html", method=RequestMethod.GET)
@ResponseBody 
public MyreturnObject getPostLogout(){
    return new ReturnObject(true,true,false);
}

Spring+Jackson will take care of serializing the Object to JSON and setting the correct mime type. See this previous answer of mine for a full working version.
