小白一个，第一次使用springboot，想用mybatis来做dao层框架，按网上资料进行了一下配置但是出现了一个错误，我不知道我的配置错在哪儿，麻烦大神帮忙指导一下，谢谢：
application.properties配置如下：
mybatis.mapper-locations=classpath:mapper/mapper/*Mapper.xml
mybatis.config-location=classpath:mapper/sqlMapConfig.xml
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=root
接着是sqlMapConfig.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
然后是mapp.xml的配置
select * from user
sercive层代码如下：
package com.tky.test.service;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.tky.test.dao.UserMapper;
import com.tky.test.emit.User;
@Service(value="userService")
public class UserServiceImpl implements UserService{
@Resource
private UserMapper userMapper;
@Override
public List<User> findUser() {
List<User> findAll = userMapper.findAll();
return findAll;
}
}
然后是Mapper接口的代码：
package com.tky.test.dao;
import java.util.List;
import com.tky.test.emit.User;
public interface UserMapper {
public List<User> findAll();
}
在下面是controller层的:
@RestController(value="userController")
public class UserController {
@Resource
private UserService userService;
@RequestMapping("my")
public List<User> getMy(){
List<User> findUser = userService.findUser();
return findUser;
}
}
最后是springboot的主函数代码:
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
@MapperScan(value="com.tky.test.dao")
public class Driver {
public static void main(String[] args) {
//项目入口
SpringApplication.run(Driver.class,args);
}
@Bean
public SqlSessionFactory sessionFactory() throws Exception{
SqlSessionFactory sqlSessionFactory =
new SqlSessionFactoryBean().getObject();
return sqlSessionFactory;
}
}
最后的报错信息很长是这样的:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userMapper' defined in file [D:\work\tky_workspace\Test_SpringBoot\target\classes\com\tky\test\dao\UserMapper.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in com.tky.test.Driver: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sessionFactory' threw exception; nested exception is java.lang.IllegalArgumentException: Property 'dataSource' is required
有没有大神能看明白的帮忙指导一下，谢谢
