springboot如何配置全局的接口返回都采用utf-8编码
1、新建一个实现WebMvcConfigurationSupport接口的实现类
@Configuration
public class MessageMvcConfiguration extends WebMvcConfigurationSupport {
//覆写extendMessageConverters方法即可
// @Override
protected void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
for (HttpMessageConverter<?> converter :converters){
if(converter instanceof StringHttpMessageConverter){
//将StringHttpMessageConverter改为utf-8
((StringHttpMessageConverter)converter).setDefaultCharset(StandardCharsets.UTF_8);
}
}
super.extendMessageConverters(converters);
}
}
