我正在使用带有默认application.yml
属性文件的Spring Boot 2.0。我想将它拆分为单独的属性文件,因为它变得很大
另外,我想编写测试来检查属性的正确性:将在生产应用程序上下文中出现的值(而不是测试对象)。
这是我的属性文件: src / main / resources / config / custom.yml
my-property:
value: 'test'
物业类:
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
@Data
@Configuration
@ConfigurationProperties(prefix = "my-property")
@PropertySource("classpath:config/custom.yml")
public class MyProperty {
private String value;
}
测试:
import static org.junit.Assert.assertEquals;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyProperty.class)
@EnableConfigurationProperties
public class MyPropertyTest {
@Autowired
private MyProperty property;
@Test
public void test() {
assertEquals("test", property.getValue());
}
}
但测试失败并出现错误:
java.lang.AssertionError:
Expected :test
Actual :null
此外,我在null
打印应用程序时运行应用程序时看到属性值为ApplicationRunner
。
当我对所有属性使用application.yml
时,它具有相同的配置。
如何正确配置属性和测试以使其正常工作? 链接到Github repo

很明显,我找到了在我的应用中使用自定义yaml属性的正确方法。
问题是Spring不支持yaml文件为@PropertySource
(link to issue)。以下是如何处理spring documentation中描述的解决方法
因此,为了能够从您需要的yaml文件加载属性:
*实施EnvironmentPostProcessor
*在spring.factories
请访问此github repo以获取完整示例。
另外,非常感谢您的支持,伙计们!

@TestPropertySource
可以解决您的问题。
@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyProperty.class)
@TestPropertySource(locations="classpath:test.properties")
public class MyPropertyTest {
@Autowired
private MyProperty property;
@Test
public void test() {
assertEquals("test", property.getValue());
}
}
希望它有所帮助。

我参加聚会有点晚了,但这也可能有所帮助。到目前为止,作为答案提供的解决方案是最好的方法,但这是我使用的替代方法
使用配置文件并修改PropertySoucesPlaceHolderConfiguration bean以根据配置文件加载必要的属性文件。它将application.properties加载为默认属性,但其他属性文件-oauth_DEV和oauth_QA会根据配置文件集加载。
@Bean
public PropertySourcesPlaceholderConfigurer propertyPlaceholderConfigurerconfigurer() {
System.out.println("Inside Placeholder bean");
PropertySourcesPlaceholderConfigurer cfg = new PropertySourcesPlaceholderConfigurer();
ClassPathResource cls1= new ClassPathResource("application.properties");
ClassPathResource cls2 = null;
Map<String, Object> propMap = ((ConfigurableEnvironment) ctx.getEnvironment()).getSystemProperties();
for(Map.Entry<String, Object> entrySet: propMap.entrySet()) {
System.out.println("Map.Key:"+entrySet.getKey()+" Map.valiue:"+entrySet.getValue());
}
List<String> profiles= Arrays.asList(ctx.getEnvironment().getActiveProfiles());
if(profiles == null || profiles.isEmpty()) {
if(!propMap.containsKey("spring.profiles.active")) {
cls2 = new ClassPathResource("oauth-default.properties");
} else {
cls2 = new ClassPathResource("oauth-"+propMap.get("spring.profiles.active")+".properties");
}
}else {
for(String profile:profiles) {
if(profile.equalsIgnoreCase("DEV")) {
cls2 = new ClassPathResource("oauth-DEV.properties");
}else if(profile.equalsIgnoreCase("QA")) {
cls2 = new ClassPathResource("oauth-QA.properties");
}else if (profile.equalsIgnoreCase("UAT")) {
cls2 = new ClassPathResource("oauth-UAT.properties");
}else if(profile.equalsIgnoreCase("PROD")){
cls2 = new ClassPathResource("oauth-PROD.properties");
}else {
cls2 = new ClassPathResource("oauth-default.properties");
}
}
}
cfg.setLocations(cls1,cls2);
//cfg.setPlaceholderPrefix("#{");
return cfg;
}
然后创建另一个基于前缀-“ security.oauth2.client”读取属性的bean
@Configuration
@ConfigurationProperties(prefix="security.oauth2.client")
public class OauthSecurityConfigurationDto {
private String clientId;
private String clientSecret;
private String scope;
private String accessTokenUri;
private String userAuthorizationUri;
private String grantType;
private String resourceIds;
private String registeredRedirectUri;
private String preEstablishedRedirectUri;
private String useCurrentUri;
private String userInfoUri;
public String getClientId() {
return clientId;
}
public void setClientId(String clientId) {
this.clientId = clientId;
}
public String getClientSecret() {
return clientSecret;
}
public void setClientSecret(String clientSecret) {
this.clientSecret = clientSecret;
}
public String getScope() {
return scope;
}
public void setScope(String scope) {
this.scope = scope;
}
public String getAccessTokenUri() {
return accessTokenUri;
}
public void setAccessTokenUri(String accessTokenUri) {
this.accessTokenUri = accessTokenUri;
}
public String getUserAuthorizationUri() {
return userAuthorizationUri;
}
public void setUserAuthorizationUri(String userAuthorizationUri) {
this.userAuthorizationUri = userAuthorizationUri;
}
public String getGrantType() {
return grantType;
}
public void setGrantType(String grantType) {
this.grantType = grantType;
}
public String getResourceIds() {
return resourceIds;
}
public void setResourceIds(String resourceIds) {
this.resourceIds = resourceIds;
}
public String getRegisteredRedirectUri() {
return registeredRedirectUri;
}
public void setRegisteredRedirectUri(String registeredRedirectUri) {
this.registeredRedirectUri = registeredRedirectUri;
}
public String getPreEstablishedRedirectUri() {
return preEstablishedRedirectUri;
}
public void setPreEstablishedRedirectUri(String preEstablishedRedirectUri) {
this.preEstablishedRedirectUri = preEstablishedRedirectUri;
}
public String getUseCurrentUri() {
return useCurrentUri;
}
public void setUseCurrentUri(String useCurrentUri) {
this.useCurrentUri = useCurrentUri;
}
public String getUserInfoUri() {
return userInfoUri;
}
public void setUserInfoUri(String userInfoUri) {
this.userInfoUri = userInfoUri;
}
}
记住设置器很重要,因为ConfigurationProperties
仅在定义了getter和setter时才将值加载到类的属性中
现在,我们可以在需要的地方自动关联依赖项并使用该属性。

如果这是您的确切代码,则意味着您正在从错误的属性文件中读取您的属性。
将您的媒体资源替换为此行。
@PropertySource("classpath:config/services.yml")
