`JSON` Rest请求JSON编码
`MULTIPART` 文件上传编码，浏览器会把整个表单以控件为单位分割，并为每个部分加上Content-Disposition，并加上分割符(boundary)
`TEXT_HTML` text/html编码
`TEXT_PLAIN` text/plain编码
`TEXT_XML` Rest请求text/xml编码
`XML` Rest请求XML编码

```
public static ContentType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (ContentType c : ContentType.values())
    System.out.println(c);
```

    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ContentType valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getValue
```
public String getValue()
```
    获取value值
    
    Returns:
    
    value值
