MyBatis3 & xxx is ambiguous in Mapped Statements collection异常

MyBatis3 模糊查询 & xxx is ambiguous in Mapped Statements collection异常

转载

模糊查询:

工作中用到,写三种用法吧

 

1. sql中字符串拼接

   SELECT * FROM tableName WHERE name LIKE CONCAT(CONCAT('%', #{text}), '%');

 

2. 使用 ${...} 代替 #{...}

   SELECT * FROM tableName WHERE name LIKE '%${text}%'; 

 

3. 程序中拼接

   Java

   // or String searchText = "%" + text + "%";

   String searchText = new StringBuilder("%").append(text).append("%").toString();

   parameterMap.put("text", searchText);

 

   SqlMap.xml

   SELECT * FROM tableName WHERE name LIKE #{text};

 

异常:

java.lang.IllegalArgumentException: modify is ambiguous in Mapped Statements collection (try using the full name including the namespace, or rename one of the entries)
 at org.apache.ibatis.session.Configuration$StrictMap.get(Configuration.java:466)
 at org.apache.ibatis.session.Configuration.getMappedStatement(Configuration.java:349)
 at org.apache.ibatis.binding.MapperMethod.setupCommandType(MapperMethod.java:137)
 at org.apache.ibatis.binding.MapperMethod.(MapperMethod.java:46)
 at org.apache.ibatis.binding.MapperProxy.invoke(MapperProxy.java:34)
 at $Proxy10.modify(Unknown Source)

 

抛出这个异常的原因可能是因为mapper.xml配置文件中的namespace属性配置错误造成的,没有根据命名空间的值(全称类名)找到相应映射接口。
