【spring reference】@responsebody注解 -凯发ag旗舰厅登录网址下载

为什么80%的码农都做不了架构师？>>>   

spring reference写到：

mapping the response body with the @responsebody annotation

the @responsebodyannotation is similar to @requestbody. this annotation can be put on a method and indicates that the return type should be written straight to the http response body (and not placed in a model, or interpreted as a view name).
for example:
@requestmapping(value = "/something", method = requestmethod.put)
@responsebody
public string helloworld() {
    return "hello world";
}
 
the above example will result in the text hello world  being written to the http response stream. as with @requestbody, spring converts the returned object to a response body by using an httpmessageconverter. for more information on these converters, see the previous section and message converters.
jast领会到：

使用@responsebody注解映射响应体
@responsebody注解和@requestbody注解类似。这个注解能使用在方法上，用来指明该方法的返回类型将直接作为响应给http请求(不会换成model,或解析为视图的名字)

举个例子：
@requestmapping(value = "/something", method = requestmethod.put)
@responsebody
public string helloworld() {
    return "hello world";
}
这上面的例子将以text/html形式响应http请求。和@requestbody一样，spring使用httpmessageconverter来将方法的返回值进行类型转换的。对于不同的返回值spring会转化成不同的 类型。
