父工程

idea点击spring-boot-starter-parent找到父工程spring-boot-dependencies模仿配置

SpringBoot整合测试

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
</dependency>

• 测试

import com.fly.IndexController;
import junit.framework.TestCase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

@SpringBootTest(classes = IndexController.class)
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class TestIndexController {
    @Autowired
    private IndexController indexController;

    @Test
    public void test1(){
        //断言indexController的first()返回"hello:fly"
        TestCase.assertEquals(this.indexController.first(),"hello:fly");
    }
}

SpringBootApplication注解

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

@EnableAutoConfiguration
@ComponentScan("com.fly")
public class SpringDemoApp {
    public static void main(String[] args){
        SpringApplication.run(SpringDemoApp.class,args);
    }
}

使用组合注解SpringBootApplication注解：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

//@EnableAutoConfiguration
//@ComponentScan("com.fly")
@SpringBootApplication(scanBasePackages = {"com.fly"})//默认是本包及子报
public class SpringDemoApp {
    public static void main(String[] args){
        SpringApplication.run(SpringDemoApp.class,args);
    }
}
