這篇文章主要介紹了SpringBoot打印POST請(qǐng)求原始入?yún)ody體方式，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教

SpringBoot打印POST請(qǐng)求原始入?yún)ody體

1、首先定義過(guò)濾器配置

package com.choice.o2o.device.common.config; 
import com.choice.o2o.device.common.filter.LogFilter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration; 
@Configuration
public class FilterConfig {
 
    @Bean
    public FilterRegistrationBean registFilter() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new LogFilter());
        registration.addUrlPatterns("/*");
        registration.setName("LogFilter");
        registration.setOrder(1);
        return registration;
    }
}

2、實(shí)現(xiàn)1中的過(guò)濾器
