测试性能:
package com.sandbox.test;
import lombok.Getter;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
@Component
@PropertySource("classpath:new-test.properties")
public class TestProperties {
@Getter
@Value("${homepage.url}")
private String homePageUrl;
}
配置:
package com.sandbox.test;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@ComponentScan(basePackages = {"com.sandbox"})
public class SpringContext {
}
new-test.properties位于 /src/test/resources 中的文件内容:
homepage.url=https://tst.mysite.com
课堂上进行了两次测试MyTest,第一个 - 不起作用,第二个 - 工作正常:
package com.sandbox.test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.testng.Assert;
import org.testng.annotations.Test;
@ContextConfiguration(classes = {SpringContext.class})
public class MyTest {
@Autowired
private TestProperties testProperties;
@Test
public void thisDoesntWork() {
Assert.assertNotNull(testProperties);
System.out.println(testProperties.getHomePageUrl());
}
@Test
public void thisWorks() {
AnnotationConfigApplicationContext appContext = new AnnotationConfigApplicationContext(SpringContext.class);
TestProperties testProps = appContext.getBean(TestProperties.class);
Assert.assertNotNull(testProps);
System.out.println(testProps.getHomePageUrl());
}
}
目标是在不使用 xml 的情况下自动装配类testProperties中的字段。但目前是. 注释已经到位,但我缺少什么?...MyTestnull@Component@ComponentScan
