Question

我使用@responseBody编写了一个简单的基于休息的控制器，我期望返回一个JSON。不知怎的，我无法按预期工作。当我运行网址"http://localhost:8080/my-webapp/amazon/rips" ..返回错误

时

HTTP状态406 -JBWEB000126：此请求标识的资源只能根据请求“接受”标题生成具有不可接受特征的响应。 有人可以伸出援助之手。

Mycontroller如下：

@Controller
@RequestMapping("/amazon")
public class JsonController {

@RequestMapping(value="/{name}", method = RequestMethod.GET,produces = "application/json")
public @ResponseBody
Book getShopInJSON(@PathVariable String name) {

    Book book = new Book();
    book.setName(name);
    book.setAvailablity(false);

    return book;

}

图书课程如下：

public class Book {

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public boolean isAvailablity() {
    return availablity;
}

public void setAvailablity(boolean availablity) {
    this.availablity = availablity;
}

private String name ;
private boolean availablity;

}

displatcher servlet如下：

在@CodeChimp的帮助下，我意识到我发送的请求没有正确的接受标头。我使用了Chromes“Advanced Rest client”并使用key =“accept”和value =“application / json”添加了标题，我能够得到正确的响应。

<强>更新我发现调度程序servlet中没有添加<mvc:annotation-driven />，它使用@RequestBody / @ ResponseBody配置对HTTP消息转换的支持。一旦我添加了这条信息，就不需要使用任何高级的Rest客户端。

Spring 3.1.1和json获取错误406
