Caused by: java.lang.IllegalStateException: parameter name is not present,
method=org.example.controller.HelloController:result
solution:
change pom.xml, add compiler argument: -parameters, for example:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerArgument>-parameters</compilerArgument>
</configuration>
</plugin>
