配置代码

去除路径参数的前后空格

import org.springframework.beans.propertyeditors.StringTrimmerEditor;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.InitBinder;@ControllerAdvice
public class GlobalControllerAdvice {/*** Get请求参数去除空格* @param binder*/@InitBinderpublic void stringTrimmerEditor(WebDataBinder binder) {binder.registerCustomEditor(String.class,new StringTrimmerEditor(true));}}

去除@RequestBody json的参数前后空格

import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.deser.std.StdScalarDeserializer;
import org.apache.commons.lang3.StringUtils;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import java.io.IOException;@Configuration
public class AppConfig {/*** 注解@RequestBody中JSON或XML对象参数，去除空格* @return*/@Beanpublic Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {return jacksonObjectMapperBuilder -> {// 为 String 类型自定义反序列化操作jacksonObjectMapperBuilder.deserializerByType(String.class, new StdScalarDeserializer<String>(String.class) {@Overridepublic String deserialize(JsonParser jsonParser, DeserializationContext ctx)throws IOException {// 去除前后空格return StringUtils.trim(jsonParser.getValueAsString());}});};}}
