2023-09-09

注意，注意，一定要注意，mybatis的jar包与mybatis-spring的jar包的版本,一定要看这两个jar包的版本下面是与java8匹配的版本

SpringMvcConfig

注意注意@PropertySource

一定要加上classpath:

如果单独加

"jdbc.properties"
的话，会报找不到找不到

jdbc.properties的错误

package com.hh.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.context.annotation.PropertySource;

/**

@Configuration
@ComponentScan("com.hh.service")
@PropertySource("classpath:jdbc.properties")
@Import({JdbcConfig.class,MybatisConfig.class})
public class SpringConfig {
