What does error NoSuchFieldException in Spring means?
security, spring
Solution
There is no error. Only a stack trace at debug level where Spring is trying to locate the right constructor for the login success handler (the default has 2 constructors and only one will match the String provided as an argument, i.e. "/admin/login"). You can ignore it or you can switch it off (debug logging at that level is not often very helpful, and you probably wouldn't want it on in production).
Problem
``` 2723 [Thread-1] DEBUG org.springframework.core.env.StandardEnvironment - Adding [systemEnvironment] PropertySource with lowest search precedence 2723 [Thread-1] DEBUG org.springframework.core.env.StandardEnvironment - Initialized StandardEnvironment with PropertySources [systemProperties,systemEnvironment] 2725 [Thread-1] DEBUG org.springframework.beans.BeanUtils - No property editor [org.springframework.security.web.authentication.logout.LogoutSuccessHandlerEditor] found for type org.springframework.security.web.authentication.logout.LogoutSuccessHandler according to 'Editor' suffix convention 2726 [Thread-1] DEBUG org.springframework.beans.TypeConverterDelegate - **Field [/admin/login] isn't an enum value** java.lang.NoSuchFieldException: /admin/login at java.lang.Class.getField(Class.java:1537) at org.springframework.beans.TypeConverterDelegate.attemptToConvertStringToEnum(TypeConverterDelegate.java:287) at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:218) at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:92) at org.springframework.beans.BeanWrapperImpl.convertIfNecessary(BeanWrapperImpl.java:451) ``` I have `/admin/login` as a mapping in one controller: ``` @RequestMapping(value="/admin/login", method=RequestMethod.GET) public ModelAndView getLoginPage(@RequestParam(value="failedAttempt", required=false) boolean failedAttempt, ModelMap model) { ``` Other than that, this string is mentioned in the `spring-security.xml`.
