foo-test.properties (测试环境)
foo-pro.properties (生产环境)
需要根据spring.profiles.active 切换
import java.io.IOException; import java.util.Properties; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.ApplicationContext; import org.springframework.context.annotation.Bean; import org.springframework.core.io.ClassPathResource; import org.springframework.stereotype.Component; @Component public class FooProperties { public static String oneProp; @Autowired public void setOneProp(@Value("#{foo['one.prop']}") String oneProp) { FooProperties.oneProp = oneProp; } @Bean(name = "foo") public Properties getProperties(ApplicationContext ac) { Properties properties = new Properties(); try { String path = "foo%s.properties"; String[] profiles = ac.getEnvironment().getActiveProfiles(); if (profiles != null && profiles.length > 0 && !"default".equals(profiles[0])) { path = String.format(path, "-" + profiles[0]); } else { path = String.format(path, ""); } properties.load(new ClassPathResource(path).getInputStream()); } catch (IOException e) { throw new RuntimeException("failed for loading file", e); } return properties; } }
这个类有个有意思的地方,@Bean 之后,入参ApplicationContext 可以自动注入,不需要加其他配置;
这里不推荐激活多个profiles ,默认取激活的第一个profile
比如:
spring: profiles: active: - test
则会加载 foo-test.properties 中的属性
单元测试中激活profiles
@ContextConfiguration(locations = { "classpath:xxx.xml" }) @RunWith(SpringJUnit4ClassRunner.class) @org.springframework.test.context.ActiveProfiles(value="test") public class FooTest { ... }
