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

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

即在mybatis中dao接口与mapper配置文件在做映射绑定的时候出现问题

简单说，就是接口与xml要么是找不到，要么是找到了却匹配不到

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.youxiu.edu.mapper.UserMapper.findUserById
    at org.apache.ibatis.binding.MapperMethod$SqlCommand.<init>(MapperMethod.java:223)
    at org.apache.ibatis.binding.MapperMethod.<init>(MapperMethod.java:48)
    at org.apache.ibatis.binding.MapperProxy.cachedMapperMethod(MapperProxy.java:59)
    at org.apache.ibatis.binding.MapperProxy.invoke(MapperProxy.java:52)
    at com.sun.proxy.$Proxy18.findUserById(Unknown Source)

在生成的target内可以发现没有mapper.xml,解决方法是在Dao的pom内配置mybatis-plus(只有mybatis.mapper-locations不起作用)

如图:

代码:

<plugin>
                    <artifactId>maven-resources-plugin</artifactId>
                    <version>3.0.2</version>
                    <executions>
                        <execution>
                            <id>copy-xmls</id>
                            <phase>process-sources</phase>
                            <goals>
                                <goal>copy-resources</goal>
                            </goals>
                            <configuration>
                                <outputDirectory>${basedir}/target/classes</outputDirectory>
                                <resources>
                                    <resource>
                                        <directory>${basedir}/src/main/java</directory>
                                        <includes>
                                            <include>**/*.xml</include>
                                        </includes>
                                    </resource>
                                </resources>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>

如果以上方法解决不了,可以尝试在pom中添加如下代码:

<resources>
      <resource>
          <directory>src/main/java</directory>
          <includes>
              <include>**/*.xml</include>
          </includes>
      </resource>
</resources>
