##spring4.3 引入***.yml配置文件mysql

兩種方式

YamlPropertiesFactoryBeanredis

yml 後綴的配置文件spring

#mysql
  mysql:
        jdbc:
          url: jdbc:mysql://localhost:3306
          dirverClass: com.mysql.jdbc.Driver
          username: root
          password: root

  #redis

  #mongodb

spring 配置文件sql

<bean id="yamlProperties" class="org.springframework.beans.factory.config.YamlPropertiesFactoryBean">
   <property name="resources">
       <list>
           <value>classpath:application.yml</value>
       </list>
   </property>
 </bean>

spring 測試類mongodb

@RunWith(SpringJUnit4ClassRunner.class)
   @ContextConfiguration({"classpath:spring-beans.xml"})
   public class SpringDemo {
       @Autowired
       public ApplicationContext applicationContext;
       @Autowired
       @Qualifier("yamlProperties")
       private Properties yamlProperties;

       @Test
       public void test() {
           String jdbcurl = yamlProperties.getProperty("mysql.jdbc.url");
           String dirverClass = yamlProperties.getProperty("mysql.jdbc.dirverClass");
           String username = yamlProperties.getProperty("mysql.jdbc.username");
           String password = yamlProperties.getProperty("mysql.jdbc.password");
           System.out.println(jdbcurl);
           System.out.println(dirverClass);
           System.out.println(username);
           System.out.println(password);
       }
      }

YamlMapFactoryBeanapp

yml 後綴的配置文件curl

#mysql
  mysql:
        jdbc:
          url: jdbc:mysql://localhost:3306
          dirverClass: com.mysql.jdbc.Driver
          username: root
          password: root

  #redis

  #mongodb

spring 配置文件測試

<bean id="yamlMap" class="org.springframework.beans.factory.config.YamlMapFactoryBean">
          <property name="resources">
              <list>
                  <value>classpath:application.yml</value>
              </list>
          </property>
      </bean>

spring 測試類url

@RunWith(SpringJUnit4ClassRunner.class)
  	@ContextConfiguration({"classpath:spring-beans.xml"})
  	public class SpringDemo {

  	@Autowired
  	public ApplicationContext applicationContext;

  	@Autowired
  	private Map<String, Object> yamlMap;

  	@Test
  	public void test() {
  	Map<String, Object> enviroment = (Map<String, Object>) yamlMap.get("yamlMap");
  	Map<String, Object> mysql = (Map<String, Object>) enviroment.get("mysql");
  	Map<String, Object> jdbc = (Map<String, Object>) mysql.get("jdbc");
  	String url = (String) jdbc.get("url");
  	System.out.println(url);
  	}
  	}
