加班使我熟睡

我想在spring cloud alibaba里面，让其他业务模块 的entity mapper service 都集中到 common 里面？

使用的是 spring cloud alibaba 2021.0.1 + spring boot 2.6.4 目录布局： 1、common模块：存放 model、mapper、service、impl、连接数据库、统一异常处理、redis josn数据格式化、统一响应、swagger、mp、cors 2、merchant模块（商户端）：主要编辑controller对外开放api接口 3、supply模块（供货商）：主要编辑controller对外开放api接口 问题描述： 目前在做 merchant模块，启动时提示错误： Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springApplicationAdminRegistrar' defined in class path resource [org/springframework/boot/autoconfigure/admin/SpringApplicationAdminJmxAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.management.InstanceAlreadyExistsException: org.springframework.boot:type=Admin,name=SpringApplication "de153284ee0293c1957a1adb5b4189c.png" (https://wmprod.oss-cn-shanghai.aliyuncs.com/c/user/20241005/8243f67869e656150c1229aeba1c8e5a.png) 尝试3~5小时没解决，特来思否求助大佬们 特别描述： 1、目前swagger2实际测试成功。将swagger2全部内容放到common模块，在商户端编写controller时，进行添加注解接口：启动 swagger2可以显示商户端的端口中打开文档地址显示controller中定义的接口文档 尝试失败过的方法： 1、在启动类上加包扫描：结果失败，提示另一个错误 // @SpringBootApplication @SpringBootApplication(scanBasePackages = "com.quanneng") @Slf4j @MapperScan("com.quanneng.mapper") public class MerchantApiApplication { …… } Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springApplicationAdminRegistrar' defined in class path resource [org/springframework/boot/autoconfigure/admin/SpringApplicationAdminJmxAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.management.InstanceAlreadyExistsException: org.springframework.boot:type=Admin,name=SpringApplication -->后百度，解决无果 2、尝试 @ComponentScan({"com.*"}) public class MerchantApiApplication { …… } Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'merchantController': Unsatisfied dependency expressed through field 'merchantService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'merchantService': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'merchantMapper' defined in file [D:\biancheng\git_cangku_java_spring_cloud_alibaba\liuliang_mall_java\common\target\classes\com\quanneng\mapper\MerchantMapper.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required -->配置了 mybatisPlusConfig 无果、添加 datasource 到 merchant 模块yml文件 无果。

引入sentinel导致的multiple SLF4J bindings问题，写了exclusion不生效？

项目引入sentinel之后，启动报错multiple SLF4J bindings，写了exclusion，把slf4j排除后，依然报错， com.alibaba.cloud spring-cloud-starter-alibaba-sentinel 2.2.9.RELEASE org.slf4j slf4j-log4j12 "C:\Program Files\Java\jdk1.8.0_301\bin\java.exe" -agentlib:jdwp=transport=dt_socket,address=127.0.0.1:58922,suspend=y,server=n -XX:TieredStopAtLevel=1 -noverify -Dspring.output.ansi.enabled=always -Dcom.sun.management.jmxremote -Dspring.jmx.enabled=true -Dspring.liveBeansView.mbeanDomain -Dspring.application.admin.enabled=true -javaagent:C:\Users\issuser\AppData\Local\JetBrains\IntelliJIdea2022.3\captureAgent\debugger-agent.jar -Dfile.encoding=UTF-8 -classpath C:\Users\issuser\AppData\Local\Temp\classpath839542257.jar com.haier.cosmo.im.base.Application Connected to the target VM, address: '127.0.0.1:58922', transport: 'socket' SLF4J: Class path contains multiple SLF4J bindings.
