解决异常Error creating bean with name 'xxxxxController': Unsatisfied dependency expressed through field解决：检查usermapper.xml的文件配置，特别是resultType和parameterType

<select id="findUserByName" resultType="java.util.HashMap">
        SELECT * FROM test where id = #{id}
    </select>
```javascript
<insert id="insertUser" parameterType="com.ggit.pay.entity.User"
        keyProperty="id" useGeneratedKeys="true">
        INSERT INTO test(id,userName,passWord)
        VALUES (#{id},#{userName, jdbcType=VARCHAR},#{passWord, jdbcType=VARCHAR} )
    </insert>

本数据库，application.yml文件中url配置错误解决：需添加serverTimezone时区url: jdbc:mysql://127.0.0.1:3306/agg_pay?allowMultiQueries=true&useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
完整配置

```java
mysql：spring:
  datasource:
    username: root
    password: wshy0924
    url: jdbc:mysql://127.0.0.1:3306/agg_pay?allowMultiQueries=true&useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
    driver-class-name: com.mysql.cj.jdbc.Driver

配置mybatis：注意mapper-locations: classpath:mapper/*Mapper.xml与项目中对应

mybatis:
  mapper-locations: classpath:mapper/*Mapper.xml
  type-aliases-package: com.ggit.pay.entity
