Ambiguous mapping found. Cannot map 'xxxxController' bean method

1.背景

今天要做一个demo，从github上clone一个springmvc mybatis的工程(https://github.com/komamitsu/Spring-MVC-sample-using-iBatis)

打包成war后启动报错：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping#0‘: Initialization of bean failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping found. Cannot map ‘personListController‘ bean method
public java.lang.String com.komamitsu.addressbook.controller.PersonListController.create(com.komamitsu.addressbook.domain.Person,org.springframework.validation.BindingResult)
to {[/person/create],methods=[POST],params=[],headers=[],consumes=[],produces=[],custom=[]}: There is already ‘personController‘ bean method
public java.lang.String com.komamitsu.addressbook.controller.PersonController.create(com.komamitsu.addressbook.domain.Person,org.springframework.validation.BindingResult) mapped.

2. 分析情况

上述情况

1. 原因1：bean重复初始化：使用@controller注解初始化一次，在applicationContext中又定义一次

通过对工程原文查找，发现没有重复初始化的情况。

2. 在不同的Controller中定义的映射重复。

　　　　重点查找了报错的personListController和personController 发现映射都一致，发现问题所在。

3. 解决问题

注释掉其中一个@Controller即可

4. 验证问题

ok

java Map与Bean相互转化

import java.beans.BeanInfo; import java.beans.IntrospectionException; import java.beans.Introspector; import java.beans.PropertyDescriptor; import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.util.HashMap;

Map和Bean的相互转换

BeanUtils位于org.apache.commons.beanutils.BeanUtils下面,其方法populate的作用解释如下: 完整方法: BeanUtils.populate( Object bean, Map properties ), 这个方法会遍历map<key, value>中的key,如果bean中有这个属性,就把这个key对应的value值赋给bean的属性. 1.bean 转换成 map Person person1=new Person(); person1.

Java Map和Bean之前的转换

// Map --> Bean 2: 利用org.apache.commons.beanutils 工具类实现 Map --> Bean       public static void transMap2Bean2(Map<String, Object> map, Object obj) {           if (map == null || obj == null) {               return;           }           try {  

Ambiguous mapping found

If you have a single default method (without explicit path mapping), then all requests without a more specific mapped method found will be dispatched to it. If you have multiple such default methods, then the method name will be taken into account fo
