springboot mybatis 依赖，以下问题怎么解决
出现以下问题：
2024-04-24 14:08:23.896 WARN 29144 --- [ restartedMain] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userInfoMyBatisController': Unsatisfied dependency expressed through field 'userInfoService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userInfoService' defined in file [D:\Javaenvironment\workspace\mngsys\target\classes\soft3\mngsys\service\UserInfoService.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [org/mybatis/spring/boot/autoconfigure/MybatisAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'file [D:\Javaenvironment\workspace\mngsys\target\classes\mapping\UserInfoMapping.xml]'; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML.

Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'UserInfo'. Cause: java.lang.ClassNotFoundException: Cannot find class: UserInfo
如下是这个项目主要代码
1.这是UserInfo类代码
package soft3.mngsys.model;
public class UserInfo {
private Integer id;
private String username;
private String password;
private String sex;
private String nativeplace;
private String hobby;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getNativeplace() {
return nativeplace;
}
public void setNativeplace(String nativeplace) {
this.nativeplace = nativeplace;
}
public String getHobby() {
return hobby;
}
public void setHobby(String hobby) {
this.hobby = hobby;
}
@Override
public String toString() {
return "UserInfo{" +
"id=" + id +
", username='" + username + '\'' +
", password='" + password + '\'' +
", sex='" + sex + '\'' +
", nativeplace='" + nativeplace + '\'' +
", hobby='" + hobby + '\'' +
'}';
}
}
2.这是mapper接口的代码
package soft3.mngsys.mapper;
import org.apache.ibatis.annotations.Mapper;
import soft3.mngsys.model.UserInfo;
//import org.apache.ibatis.annotations.Mapper;
import java.util.List;
@Mapper //表示该类是一个MyBatis
//
public interface UserInfoMapper {
List<UserInfo> findUserInfoList();
}
3.这是Controller代码
package soft3.mngsys.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import soft3.mngsys.model.UserInfo;
import soft3.mngsys.service.UserInfoService;
import java.util.List;
@Controller
public class UserInfoMyBatisController {
@Autowired
private UserInfoService userInfoService;
@ResponseBody
@GetMapping("/MyBatis_userinfo_list")
public List<UserInfo> MyBatisUserInfoList(Model model){
List<UserInfo> userInfoList=userInfoService.findUserInfoList_Service();
return userInfoList;
}
@GetMapping("/MyBatis_userinfo_list_page")
public String MyBatisUserInfoPage(Model model){
List<UserInfo> userInfoList=userInfoService.findUserInfoList_Service();
model.addAttribute("Result",userInfoList);
return "result";
}
}
4.这是UserInfoService接口代码
package soft3.mngsys.service;
import org.apache.ibatis.annotations.Mapper;
import soft3.mngsys.model.UserInfo;
import java.util.List;
@Mapper
public interface UserInfoService {
List<UserInfo> findUserInfoList_Service();
}
5.这是UserInfoServiceImpl 代码
package soft3.mngsys.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import soft3.mngsys.mapper.UserInfoMapper;
import soft3.mngsys.model.UserInfo;
import javax.transaction.Transactional;
import java.util.List;
//@Service 注解是一种用于表经济服务层 Bean 的注解，将一个类声明为业务逻辑组件，并将其对象存入Spring容器中
@Service
@Transactional
public class UserInfoServiceImpl implements UserInfoService{
@Autowired //=new
private UserInfoMapper userInfoMapper;
@Override //重写方法
public List<UserInfo> findUserInfoList_Service(){
return userInfoMapper.findUserInfoList();
}
}
6.这是UserInfoMapping.xml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">
<mapper namespace="soft3.mapper.UserInfoMapper">
<select id="findUserInfoList" resultType="UserInfo">
select * from userinfo
</select>
</mapper>
7.这是pom.xml里面加的mybatis依赖代码
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.2</version>
</dependency>
8.这是配置文件里加的代码（application.properties)
#配置MyBatis
#1.配置MyBatis的xml配置文件路径
mybatis.mapper-locations=classpath:mapping/*.xml
#2.配置xml映射文件中指定的实体类别名路径
mybatis.type-aliases-package=soft3.model
