与Spring Security集成后的处理程序映射问题

Question

I have two mapping patter /userdetails one for get request and one for post request.

It was working fine till I integrated Spring authorization into my project. Now I am getting below error any idea why this is happening?

My Two mappings are like this.

@RequestMapping(value = "/userdetails* ", method = RequestMethod.GET) 

@RequestMapping(value = "/userdetails*", method = RequestMethod.POST)

Please suggest any reason for this error.

Caused by: java.lang.IllegalStateException: Cannot map handler 'LoginController' to URL path [/userdetails]: There is already handler of type [class com.sample.user.controller.MyController] mapped.

Answer 1

I faced similar kind of problem. I have defined the controller class with "@Controller" and also in the Spring-config.xml file as a bean and have injected the dependencies.

This was causing the problem. @Controller is defining the bean and again, the bean defined in the xml file is redefining the dependencies. I tried autowiring the dependency and removed it as a bean from the xml file. Then it worked.
