Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
No message available

解决方案：

@SpringBootApplication
@ServletComponentScan
public class SpringbootMybatisDruidApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootMybatisDruidApplication.class, args);
    }

}

注意：@ServletComponentScan

import com.alibaba.druid.support.http.StatViewServlet;
import javax.servlet.annotation.WebServlet;
import javax.servlet.annotation.WebInitParam;
@WebServlet(urlPatterns = "/druid/*",
        initParams={
                @WebInitParam(name="allow",value="127.0.0.1"),// IP白名单 (没有配置或者为空，则允许所有访问)
                @WebInitParam(name="deny",value="192.168.16.111"),// IP黑名单 (存在共同时，deny优先于allow)
                @WebInitParam(name="loginUsername",value="admin"),// 用户名
                @WebInitParam(name="loginPassword",value="378592175"),// 密码
                @WebInitParam(name="resetEnable",value="false")// 禁用HTML页面上的“Reset All”功能
        })
public class DruidStatViewServlet extends StatViewServlet {
    private static final long serialVersionUID = 1L;

}

DruidStatViewServlet 继承了StatViewServlet 这个。
