需要来自 RESTful Roo 应用程序的 application/json

发布于 2024-12-07 07:49:07 字数 819 浏览 6 评论 0原文

我使用以下 Roo 脚本 (Roo 1.1.5) 创建了一个基本的 RESTful Roo 应用程序。

project --topLevelPackage com.roorest
persistence setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY 
entity --class ~.domain.MyClass
field string --fieldName String1
web mvc setup
web mvc all --package ~.web
json all

当我访问要求 application/json 的 RESTful WS 时，WS 会输出一个有效的 json 正文，但是内容类型设置为 application/text （如果查看后台生成的 (aj) 控制器代码，这很有意义）。

不幸的是，我需要让 WS 返回 application/json 的内容类型。我尝试从 json-controllers 中推送必要的方法，但这似乎 1) 很麻烦，2) 并没有真正起作用（我在推送源代码时遇到了很多错误）。

可以强制 WS 在一般情况下返回 application/json 吗？例如，是否可以将 ContentNegotiatingViewResolver 与 roo 生成的 aj 控制器结合起来？（为什么 roo 生成的代码首先显式地将应用程序/文本设置为其内容类型？破解 roo JSON 插件是一个可行的解决方案吗？）

我想我真正要问的是： 您认为让 roo 脚手架应用程序通过 WS 以 application/json 形式返回域对象的最佳方法是什么？

I've created a basic RESTful Roo application using the following Roo-script (Roo 1.1.5).

project --topLevelPackage com.roorest
persistence setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY 
entity --class ~.domain.MyClass
field string --fieldName String1
web mvc setup
web mvc all --package ~.web
json all

When I access the RESTful WS asking for application/json the WS spits out a valid json body, however the content type is set to application/text (which makes perfect sense if one looks at the generated (aj) controller code ticking in the background).

Unfortunately, I need to have the WS return a content type of application/json. I've tried to push in the necessary methods from the json-controllers, however this seems 1) cumbersome, 2) not really working (I'm getting a LOT of errors with the pushed in source).

Can one force the WS return application/json on a general basis? For instance, is it possible to combine ContentNegotiatingViewResolver with the roo generated aj controllers? (And why does the roo generated code explicitly set application/text as it's content type in the first place? Is hacking the roo JSON addon a viable solution?)

I guess what I'm really asking is this: what do you think is the best way to make a roo scaffolded application return domain objects as application/json through a WS?

你解决问题了吗，因为我也有同样的问题......？

好的，我确实有一个解决方案：将方法添加到控制器中，并且不要让 AOP 框架添加它们：

@RequestMapping(headers = "Accept=application/json")
@ResponseBody
public ResponseEntity<String> listJson() {
    HttpHeaders headers = new HttpHeaders();
    headers.add("Content-Type", "application/json; charset=utf-8"); //was app/text
    return new ResponseEntity<String>(Customer.toJsonArray(Customer
            .findAllCustomers()), headers, HttpStatus.OK);
}

Did you solve the problem, because I just having the same one...?

Okay, I do have one solution: Add the methods to your controller and do not let the AOP Framework add them:

@RequestMapping(headers = "Accept=application/json")
@ResponseBody
public ResponseEntity<String> listJson() {
    HttpHeaders headers = new HttpHeaders();
    headers.add("Content-Type", "application/json; charset=utf-8"); //was app/text
    return new ResponseEntity<String>(Customer.toJsonArray(Customer
            .findAllCustomers()), headers, HttpStatus.OK);
}
