Spring Boot 字符集设置 解决中文乱码方案

在使用spring-boot开发时，程序没事的时候，往往在不经意间造成中文乱码（？？？？这样情况）

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;
    }
}
