CharacterEncodingFilter在SpringBoot中的配置

SpringMVC中有这样一个Filter专门处理编码问题的，它是`CharacterEncodingFilter`。

比如默认给response返回设定编码格式为：UTF-8，则可以通过配置CharacterEncodingFilter实现、

所以在SpringMVC项目中使用，可以参考如下配置：

<filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

SpringBoot对`CharacterEncodingFilter`也有支持，只需如下配置

# 设置的编码，默认为：UTF-8
    spring.http.encoding.charset=UTF-8
    
    # 是否启用CharacterEncodingFilter，如果不配置也代表true
    spring.http.encoding.enabled=true
    
    # 是否强制设置请求和响应的编码格式为设置的编码格式
    spring.http.encoding.force=
    
    # 是否强制设置请求的编码格式为设置的编码格式
    spring.http.encoding.force-request=
    
    # 是否强制设置响应的编码格式为设置的编码格式
    spring.http.encoding.force-response=

另外tomcat也可以配置，类似以前去配置tomcat的server.xml文件

**server.tomcat.uri-encoding**=UTF-8 \# Character encoding to use to decode the URI
