你的mybatis配置文件指向错误或者mybatis配置文件中没有任意一个sql语句节点
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 实体类,简称 -设置别名 -->
<typeAliases>
<typeAlias alias="User" type="com.tgb.model.UserEntity" />
</typeAliases>
<!-- 实体接口映射资源 -->
<!--
说明：如果xxMapper.xml配置文件放在和xxMapper.java统一目录下，mappers也可以省略，因为org.mybatis.spring.mapper.MapperFactoryBean默认会去查找与xxMapper.java相同目录和名称的xxMapper.xml
-->
<mappers>
<mapper resource="com/tgb/mapper/userMapper.xml" />
</mappers>
</configuration>
这个就是我的mybatis的配置文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--
namespace：必须与对应的接口全类名一致
id:必须与对应接口的某个对应的方法名一致
-->
<mapper namespace="com.tgb.mapper.UserMapper">
<insert id="save" parameterType="com.tgb.model.UserEntity">
insert into t_user(user_name,user_age) values(#{userName},#{userAge})
</insert>
<update id="update" parameterType="com.tgb.model.UserEntity">
update t_user set user_name=#{userName},user_age=#{age} where user_id=#{id}
</update>
<delete id="delete" parameterType="java.lang.Integer">
delete from t_user where user_id=#{id}
</delete>
<!-- mybsits_config中配置的alias类别名,也可直接配置resultType为类路劲 -->
<select id="findById" parameterType="java.lang.Integer" resultType="com.tgb.model.UserEntity">
select user_id id,user_name userName,user_age age from t_user where user_id=#{id}
</select>
<select id="findAll" resultType="com.tgb.model.UserEntity">
select user_id id,user_name userName,user_age age from t_user
</select>
</mapper>
这个是mapper.xml文件 是不是这个地方有问题

应该是你把MyBatis的配置文件和需要映射的文件弄错了，还有可能就是版本的问题，把代码粘贴出来看看。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 实体类,简称 -设置别名 -->
<typeAliases>
<typeAlias alias="User" type="com.tgb.model.UserEntity" />
</typeAliases>
<!-- 实体接口映射资源 -->
<!--
说明：如果xxMapper.xml配置文件放在和xxMapper.java统一目录下，mappers也可以省略，因为org.mybatis.spring.mapper.MapperFactoryBean默认会去查找与xxMapper.java相同目录和名称的xxMapper.xml
-->
<mappers>
<mapper resource="com/tgb/mapper/userMapper.xml" />
</mappers>
</configuration>
这个就是mybatis的配置文件
