spring @Cacheable 使用参数名报错 java.lang.IllegalArgumentException: Null key returned for cache operation

版本

spring-boot:3.2.1

现象

项目parent没有使用spring-boot-starter-parent

使用@Cacheable注解方法，key设置为方法参数名时报错如下：

Caused by: java.lang.IllegalArgumentException: Null key returned for cache operation [Builder[…使用@Cacheable注解的方法] caches=[…] | key=‘#方法参数名’ | keyGenerator=‘’ | cacheManager=‘’ | cacheResolver=‘’ | condition=‘’ | unless=‘’ | sync=‘false’]. If you are using named parameters, ensure that the compiler uses the ‘-parameters’ flag.

解决

pom.xml 添加配置，maven编译时保留参数名

<build>
	<pluginManagement>
	<plugins>
		<plugin>
		  <groupId>org.apache.maven.plugins</groupId>
		  <artifactId>maven-compiler-plugin</artifactId>
		  <configuration>
		    <parameters>true</parameters>
		  </configuration>
		</plugin>
