Springboot项目上遇到的一些问题
问题根源都是因为没有被spring 接管到
感谢这位博主
问题一Springboot整合Web Controller未生效 访问全是404
解决办法一:
启动类上加 @ComponentScan("com.example.controller")
解决办法二:
@SpringBootApplication 后面加 (scanBasePackages = "com.example.controller")
问题二Springboot里的整合spring security 时config无法生效
解决办法一:
启动类上加 @ComponentScan("com.example.config")
解决办法二:
@SpringBootApplication 后面加 (scanBasePackages = "com.example.config")
其他包类如果有未生效，操作同理
简写：
详细代码如下
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
/**
* @author CodeHaywire
*/
@ComponentScan({"com.example.controller", "com.example.config"})
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @author CodeHaywire
*/
@SpringBootApplication(scanBasePackages = {"com.example.controller","com.example.config"})
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
