SpringBoot配置文件

编码配置(CharacterEncodingFilter)

spring web项目中需要在添加CharacterEncodingFilter

springboot中只需要在配置文件中添加以下配置

spring.http.encoding.charset=UTF-8

spring.http.encoding.enabled=true 

spring.http.encoding.force=true 

#### yml格式 ``` spring: http: encoding: charset: UTF-8 enabled: true force: true

server:
tomcat:
uri-encoding: UTF-8

参考springboot官方文档:
https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html


有以属性可以配置

### HTTP encoding (HttpEncodingProperties)
spring.http.encoding.charset=UTF-8 # Charset of HTTP requests and responses. Added to the "Content-Type" header if not set explicitly.
spring.http.encoding.enabled=true # Whether to enable http encoding support.
spring.http.encoding.force= # Whether to force the encoding to the configured charset on HTTP requests and responses.
spring.http.encoding.force-request= # Whether to force the encoding to the configured charset on HTTP requests. Defaults to true when "force" has not been specified.
spring.http.encoding.force-response= # Whether to force the encoding to the configured charset on HTTP responses.
spring.http.encoding.mapping= # Locale in which to encode mapping.
另外web窗口 tomcat可以配置

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

### 向Spring注册一个自定义的StringHttpMessageConverter用于string转码

// 基于Springboot2.0.1.RELEASE

import com.simply.zuozuo.interceptor.HandleInterceptorImpl;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.web.servlet.config.annotation.ContentNegotiationConfigurer;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import java.nio.charset.Charset;
import java.util.List;

@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {

@Bean
public HttpMessageConverter<String> responseBodyConverter() {
    return new StringHttpMessageConverter(Charset.forName("UTF-8"));
}

@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    converters.add(responseBodyConverter());
    // 这里必须加上加载默认转换器，不然bug玩死人，并且该bug目前在网络上似乎没有解决方案
    // 百度，谷歌，各大论坛等。你可以试试去掉。
    addDefaultHttpMessageConverters(converters);
}

@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
    configurer.favorPathExtension(false);
}

}
