这个问题排查了很久了没有解决:
原先我是将 xml 放在 resources 下的,架构师让把 mybatis 的 xml 文件放在 src/main/java 下,所以需要配置 resources 资源:
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.ftl</include>
<include>**/*.properties</include>
<include>**/*.yml</include>
<include>static/**</include>
<include>templates/**</include>
<include>db/**</include>
<include>**/*.sql</include>
<include>swagger-resources/**</include>
</includes>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
mybatis:
type-aliases-package: com.xxx.xxx.*.*.entity
mapper-locations: classpath*:com/xxxx/backend/**/*.xml
mapper:
identity: MYSQL
@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
@MapperScan({"com.xxx.xxx.mapper"})
@Slf4j
public class SystemAdminMain8080 {
public static void main(String[] args) throws Exception {
log.info("springboot application SYSTEMADMIN is starting");
SpringApplication.run(SystemAdminMain8080.class, args);
}
}
当只配置main
下的@MapperScan
扫描时(使用tk.mybatis
的注解),不配置yml
下的
mapper-locations: classpath*:com/xxxx/backend/**/*.xml
。
启动正常,tk.mybatis
通用 sql 也正常。只是自定义 xml 的 sql 会出现Invalid bound statement (not found)
。
考虑 xml 文件是写在src/main
下的,所以追加配置了:
mapper-locations: classpath*:com/xxxx/backend/**/*.xml
配置后发现启动直接报错: 日志长度过长,所以放在完整日志信息放在这里: https://paste.ubuntu.com/p/JTTnzWxfxM/
