  • springboot使用工具类无需注入获取yml配置项

    1.新建 BeanConfiguration 类,用于项目启动构造我们的工具类

    package webapp.config;
    
    import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.core.io.ClassPathResource;
    import org.springframework.core.io.Resource;
    import webapp.util.YamlConfigurerUtil;
    import java.util.Properties;
    
    @Configuration
    public class BeanConfiguration {
        @Bean
        public YamlConfigurerUtil ymlConfigurerUtil() {
            //1:加载配置文件
            Resource app = new ClassPathResource("application.yml");
            YamlPropertiesFactoryBean yamlPropertiesFactoryBean = new YamlPropertiesFactoryBean();
            // 2:将加载的配置文件交给 YamlPropertiesFactoryBean
            yamlPropertiesFactoryBean.setResources(app);
            // 3:将yml转换成 key:val
            Properties properties = yamlPropertiesFactoryBean.getObject();
            // 4: 将Properties 通过构造方法交给我们写的工具类
            YamlConfigurerUtil ymlConfigurerUtil = new YamlConfigurerUtil(properties);
            return ymlConfigurerUtil;
        }
    
    }

    2.工具类实现

    package webapp.util;
    
    import java.util.Properties;
    
    public class YamlConfigurerUtil {
    
        private static Properties ymlProperties = new Properties();
    
        public YamlConfigurerUtil(Properties properties){
            ymlProperties = properties;
        }
    
        public static String getStrYmlVal(String key){
            return ymlProperties.getProperty(key);
        }
    
        public static Integer getIntegerYmlVal(String key){
            return Integer.valueOf(ymlProperties.getProperty(key));
        }
    
    }

    3.调用示例

    String password = YamlConfigurerUtil.getStrYmlVal("redis.password");
