所有已实现的接口:
HttpMessageConverter<String>
```
public class StringHttpMessageConverter
extends AbstractHttpMessageConverter<String>
```
Implementation of HttpMessageConverter that can read and write strings.
By default, this converter supports all media types (*/*), and writes with a Content-Type of text/plain. This can be overridden by setting the supportedMediaTypes property.

  - setWriteAcceptCharset
```
public void setWriteAcceptCharset(boolean writeAcceptCharset)
```
    Indicates whether the Accept-Charset should be written to any outgoing request.
    Default is true.

    指定者:
    supports 在类中 AbstractHttpMessageConverter<String>
    参数:
    clazz - the class to test for support
    返回:
    true if supported; false otherwise
  - readInternal
```
protected String readInternal(Class<? extends String> clazz,

    Abstract template method that reads the actual object. Invoked from AbstractHttpMessageConverter.read(java.lang.Class<? extends T>, org.springframework.http.HttpInputMessage).
    指定者:
    readInternal 在类中 AbstractHttpMessageConverter<String>
    参数:
    clazz - the type of object to return
