1、bean注入问题
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
解决1:
由于引入的bean类 不属于启动类的子模块下,需要在启动类手动声明扫描的类
也适用于公共子模块的bean引入问题
/**指定要扫描的Mapper类的包的路径*/
@MapperScan({"com.bhl.**"})
@SpringBootApplication
public class UserApplication {
public static void main(String[] args) {
SpringApplication.run(UserApplication.class, args);
}
}
或者使用
@ComponentScan("com.bhl")
解决2:
调整目录结构,位于子目录下
2、服务启动问题
1、Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean
缺少依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
2、Unable to start embedded Tomcat
缺少tomcat容器
<!-- servlet包 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
</dependency>
3、没有主清单属性
提示错误:Unable to find main class
在父pom中移除 spring-boot-maven-plugin
<!-- <build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<excludes>
<exclude>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</exclude>
</excludes>
</configuration>
</plugin>
</plugins>
</build>-->
在存在SpringBootApplication启动类的模块中,添加
必须要指定版本
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>2.5.13</version>
</plugin>
