Springboot加载maven父子工程配置文件的方法
1、@PropertySource
父子工程同名配置文件,优先加载当前主模块的配置文件,主模块的配置文件没有加载子模块的配置文件 (默认resource下的配置文件)
@PropertySource(value={"classpath:skill-common.properties"})
2、ResourceUtils
org.springframework.util.ResourceUtils
父子工程同名配置文件,优先加载当前主模块的配置文件,主模块的配置文件没有加载子模块的配置文件(默认resource下的配置文件)
URL url = null; Properties pro = new Properties(); try { url = ResourceUtils.getURL("classpath:skill-common.properties"); pro.load(url.openStream()); } catch (FileNotFoundException e) { e.printStackTrace(); }
3、ClassPathResource
org.springframework.core.io.ClassPathResource
父子工程同名配置文件,优先加载当前主模块的配置文件,主模块的配置文件没有加载子模块的配置文件(默认resource下的配置文件)
ClassPathResource resource = new ClassPathResource("skill-common.properties"); String path = resource.getPath(); Properties pro = new Properties(); try { pro.load(resource.getInputStream()); } catch (IOException e) { e.printStackTrace(); }
4、ResourcePatternResolver 资源匹配解析器
(默认resource下的配置文件)
1、只加载主模块的前缀skill-的配置文件
ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); Resource[] resources = resolver.getResources("skill-*.properties"); Properties pro = new Properties(); for (Resource resource : resources) { String path = resource.getURL().getPath(); System.err.println(path); pro.load(resource.getInputStream()); }
2、配置文件路径加classpath*: //加载父子模块所有前缀skill-的配置文件
ResourcePatternResolver resolverAll = new PathMatchingResourcePatternResolver(); Resource[] resourcesAll = resolverAll.getResources("classpath*:skill-*.properties"); Properties prop = new Properties(); for (Resource resource : resourcesAll) { String path = resource.getURL().getPath(); System.err.println(path); prop.load(resource.getInputStream()); }
