解决Maven项目中 Invalid bound statement 无效的绑定问题

解决Maven项目中 Invalid bound statement 无效的绑定问题

问题

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):

关于这个问题，我的是 Maven 项目，在访问程序的接口时，抛出异常信息，无效的绑定语句。

在检查调用的 Mapper 接口时，发现在目标文件中没有找到 Mapper 映射的配置文件，在项目的 target 目标文件中可以看到，与接口对应的 Mapper 文件未加载，所以在程序启动时，就找不到对应的映射文件，导致的这个错误。

解决方法

在 pom 配置文件中键入 节点，并指明资源类型，这样在程序启动时，就可以正确加载配置文件了：

java中的配置资源类型：

src/main/java

&QKjlGzlt;includes>

**/*.properties

**/*.xml

false

Resource中的配置资源类型：

src/main/resources

**/*.properties

**/*.xml

false

当然项目需求可以同时键入两个：

src/main/java

**/*.properties

**/*.xml

false

src/main/resources

**/*.properties

*QKjlGz*/*.xml

false

键入 节点后，在次启动项目，在项目的 target 目标文件中，就可以看到接口对应的映射文件了，问题解决咯！！！！

开发maven时遇到无效的绑定语句（未找到）,org.apache.ibatis.binding.BindingException：

今天做一个springmvc+mybatis的maven项目时运行登录时报错，显示找不到绑定语句

我按照网上的方法怎么看都没发现自己有错误，很烦恼。但是他说找不到绑定语句，我明明绑定语句没有错误，为什么找不到呢？于是我去target文件夹看看我的classes有没有编译出来，看了之后一目了然。

我们的class文件被编译了，但是绑定语句xml文件没有被编译。

在做maven项目时，以后都要注意一个点，要在build标签里加上这个语句

src/main/java

**/*.xml

true

xml文件才能够被编译。加入之后重新编译，文件夹就多了xml文件。

问题解决。
