```
public class MappingJackson2HttpMessageConverter
extends AbstractJackson2HttpMessageConverter
```
Implementation of HttpMessageConverter that can read and write JSON using Jackson 2.x's ObjectMapper.
This converter can be used to bind to typed beans, or untyped HashMap instances.
By default, this converter supports application/json and application/*+json with UTF-8 character set. This can be overridden by setting the supportedMediaTypes property.
The default constructor uses the default configuration provided by Jackson2ObjectMapperBuilder.
Compatible with Jackson 2.6 and higher, as of Spring 4.3.
从以下版本开始:
3.1.2

```
public MappingJackson2HttpMessageConverter()
```
    Construct a new MappingJackson2HttpMessageConverter using default configuration provided by Jackson2ObjectMapperBuilder.
  - MappingJackson2HttpMessageConverter
```
public MappingJackson2HttpMessageConverter(ObjectMapper objectMapper)
```
    Construct a new MappingJackson2HttpMessageConverter with a custom ObjectMapper. You can use Jackson2ObjectMapperBuilder to build it easily.

  - setJsonPrefix
```
public void setJsonPrefix(String jsonPrefix)
```
    Specify a custom prefix to use for this view's JSON output. Default is none.
    另请参阅:
    setPrefixJson(boolean)
  - setPrefixJson
```
public void setPrefixJson(boolean prefixJson)
```
    Indicate whether the JSON output by this view should be prefixed with ")]}', ". Default is false.
    Prefixing the JSON string in this manner is used to help prevent JSON Hijacking. The prefix renders the string syntactically invalid as a script so that it cannot be hijacked. This prefix should be stripped before parsing the string as JSON.
    另请参阅:
    setJsonPrefix(java.lang.String)
  - writePrefix
```
protected void writePrefix(JsonGenerator generator,
                           Object object)
                    throws IOException
