SpringBoot配置项目字符编码

一、传统Spring提供的字符编码过滤器

 @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setForceEncoding(true);
        characterEncodingFilter.setEncoding("UTF-8");
        registration.setFilter(characterEncodingFilter);
        registration.addUrlPatterns("/*");
        return registration;
    }

在main方法上扫描此过滤器

注意：

application.properties要添加以下代码，否则上面代码不会生效

spring.http.encoding.enabled=false

二、在application.properties配置字符编码

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