spring请求参数忽略大小写

在pom.xml添加依赖

         <dependency>
            <groupId>org.codehaus.jackson</groupId>
            <artifactId>jackson-mapper-asl</artifactId>
            <version>1.9.13</version>
        </dependency>

在application.yml中

spring:
  jackson:
    mapper:
      accept-case-insensitive-properties: true

即可
