org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.bdqn.dao.BookDao.updateBook

This exception is thrown by MyBatis when it cannot find a mapped statement in the configuration. In this case, the error message specifically states that the bound statement "com.bdqn.dao.BookDao.updateBook" could not be found.

To resolve this issue, you should check your MyBatis configuration file and ensure that the statement is properly mapped. You can also verify that the namespace and ID of the statement in your Java code match the configuration file. If the issue persists, you may need to recompile your code or restart your application server.

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

在Spring Boot中，当出现"org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)"异常时，通常是因为MyBatis无法找到对应的SQL语句映射。这个异常通常发生在以下几种情况下：

1. SQL语句映射错误：检查你的Mapper XML文件或注解中的SQL语句映射是否正确。确保SQL语句的id与Mapper接口中的方法名一致，并且Mapper接口的包路径与Mapper XML文件的namespace一致。

2. Mapper接口未被扫描到：确保你的Mapper接口被正确扫描到，并且被MyBatis正确管理。可以通过在启动类上添加`@MapperScan`注解来指定Mapper接口的扫描路径。

3. Mapper接口方法名错误：检查你的Mapper接口方法名是否与Mapper XML文件或注解中的SQL语句id一致。确保方法名的大小写和参数个数类型都匹配。

4. Mapper接口方法参数错误：检查你的Mapper接口方法参数是否与Mapper XML文件或注解中的SQL语句参数一致。确保参数个数、类型和顺序都匹配。

以下是一个示例，演示了如何解决"org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)"异常：

// NewsDetailMapper.java
@Mapper
public interface NewsDetailMapper {
    List<NewsDetail> selectByExample(NewsDetailExample example);
}

// NewsDetailMapper.xml
<mapper namespace="com.team.news.mapper.NewsDetailMapper">
    <select id="selectByExample" resultType="com.team.news.model.NewsDetail">
        SELECT * FROM news_detail WHERE ...
    </select>
</mapper>

请注意，上述示例中的`NewsDetailExample`是一个自动生成的Example类，用于构建查询条件。
