使用Spring boot、testng输出ExtentReports报告不能启动Spring boot

将需要执行的测试用例全部准备好之后，相对应的testng配置也配置好，启动testng时，发现注入的实例全部都是null，根本没法用，一直报错

报错情况如下：

后面经大神指点，加入启动Spring的方法：

首先在Application中加入方法

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import org.springframework.core.io.ClassPathResource;


@SpringBootApplication(exclude = MongoAutoConfiguration.class)
@MapperScan(basePackages="com.example.demo.dao")
@Configuration
public class Application {
    public static boolean started = false;
    private static ApplicationContext applicationContext;

    public static ApplicationContext get(){
        return applicationContext;
    }
    public static void main(String[] args) {
        applicationContext = SpringApplication.run(Application.class, args);
        started = true;
    }
}

然后在测试用例代码中加入调用启动Spring boot的方法

 public static ApplicationContext applicationContext;
    @BeforeClass
    public void start(){
        if(!Application.started){
            applicationContext = SpringApplication.run(Application.class);
            Application.started = true;
        }else{
            applicationContext = Application.get();
        }
    }

这样就可以正常启动Spring boot了
