[英]Spring Profiles odd behavior
I am trying to figure out how to use Spring Profiles for testing. 我试图弄清楚如何使用Spring Profiles进行测试。 I think I do everything according to spring docs.
我认为我根据春季文档做了一切。 And in the end I got results that I cannot explain Here is the listing of my program:
最后我得到的结果我无法解释这是我的程序列表:
Here is the main config: 这是主配置:
package com.test.profiles;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import java.util.HashMap;
import java.util.Map;
@Configuration
@ComponentScan("com.test.profiles")
public class MainConfig {
@Autowired
private String helloMsg;
@Autowired
private Map<String,String> profileDependentProps;
@Bean
@Profile("default")
public String helloMsg() {
return "Hello default";
}
@Bean
@Profile("default")
public Map<String,String> profileDependentProps() {
Map<String,String> props = new HashMap<>();
props.put("1", "default");
props.put("2", "default");
props.put("3", "default");
return props;
}
}
Test configuration: 测试配置:
package com.test.profiles;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import java.util.HashMap;
import java.util.Map;
@Configuration
@Profile("dev")
public class TestConfig {
@Bean
public String helloMsg() {
return "Hello dev";
}
@Bean
public Map<String,String> profileDependentProps() {
Map<String,String> props = new HashMap<>();
props.put("1", "dev");
props.put("2", "dev");
props.put("3", "dev");
return props;
}
}
And finally my test class: 最后我的测试类:
package com.test.profiles;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.annotations.Test;
import java.util.Map;
@ContextConfiguration(classes = MainConfig.class)
@ActiveProfiles("dev")
public class ProfileTester extends AbstractTestNGSpringContextTests {
@Autowired
private String string;
@Autowired
private Map<String,String> profileDependentProps;
@Test
public void profileTest() {
System.out.println("TEST: "+string);
for(Map.Entry<String,String> entry : profileDependentProps.entrySet()) {
System.out.println(entry.getKey() + "=" + entry.getValue());
}
}
}
And odd output: 奇数输出:
[TestNG] Running:

What's with this line? 这条线有什么用? --- helloMsg=Hello dev Where is my map?
--- helloMsg = Hello dev我的地图在哪里?
By default when Spring encounters a auto wiring field of type Map<String, [type]>
it will inject a map of beans of the specific [type]
. 默认情况下,当Spring遇到
Map<String, [type]>
类型的自动布线字段时,它将注入特定[type]
的bean映射。 In your case String
. 在你的情况下
String
。 You will not get your configured map. 您将无法获得配置的地图。
See: http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#beans-autowired-annotation . 请参阅: http : //docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#beans-autowired-annotation 。
You are basically running into a corner case as you have a map with String as keys. 你基本上遇到了一个角落的情况,因为你有一个带有String作为键的地图。 To get your bean you will either have to put an
@Qualifier("profileDependentProps")
next to the @Autowired
or use @Resource("profileDependentProps")
instead of @Autowired
. 要获得你的bean,你要么必须在
@Autowired
旁边放一个@Qualifier("profileDependentProps")
,要么使用@Resource("profileDependentProps")
而不是@Autowired
。
