问题的根源是我在两个不同的package里面定义两个ConfigController。默认的，Spring以类名作为Bean名，两个不同包里面的ConfigController就变成了相同的名字。
package net.mingyang.modules.system;@Controller@RequestMapping("/control/system/config")public class ConfigController{ ......}//-----------------------------------------------------package net.mingyang.cms.controller;@Controller@RequestMapping("/control/cms/config")public class ConfigController{ ......}
解决方法是为两个@Controller指定名字：
package net.mingyang.modules.system;@Controller("/control/system/config")@RequestMapping("/control/system/config")public class ConfigController{ ......}//-----------------------------------------------------package net.mingyang.cms.controller;@Controller("/control/cms/config")@RequestMapping("/control/cms/config")public class ConfigController{ ......}
