SpringBoot 中文乱码

Spring Boot修改编码方法：

1).在application.properties里面配置

    spring.http.encoding.charset=UTF-8
    spring.http.encoding.force=true
    spring.http.encoding.enabled=true

或者在application.yml里面配置

spring:
  http:
    encoding:
      charset: UTF-8
      force: true
      enabled: true

2).在配置类中配置

@Configuration
public class EncodingFilterConfig {
    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setForceEncoding(true);
        characterEncodingFilter.setEncoding("UTF-8");
        registrationBean.setFilter(characterEncodingFilter);
        return registrationBean;
    }
}
