另一种在配置中找到键/值的方法。

...
import org.springframework.core.env.ConfigurableEnvironment;
...
@SpringBootApplication
public class MyApplication {

    @Autowired
    private ConfigurableEnvironment  myEnv;

...
  
    @EventListener(ApplicationReadyEvent.class)
    public void doSomethingAfterStartup() 
    throws Exception {
        
        LOG.info("myEnv (userBucket.path): " + myEnv.getProperty("userBucket.path"));
    }
} 

有两种方法，

你可以直接在类中使用@Value

    @Value("#{'${application yml field name}'}")
    public String ymlField;

OR

要使它干净，你可以清除@Configuration类，在那里你可以添加所有的@value

@Configuration
public class AppConfig {

    @Value("#{'${application yml field name}'}")
    public String ymlField;
}

另一种在配置中找到键/值的方法。

...
import org.springframework.core.env.ConfigurableEnvironment;
...
@SpringBootApplication
public class MyApplication {

    @Autowired
    private ConfigurableEnvironment  myEnv;

...
  
    @EventListener(ApplicationReadyEvent.class)
    public void doSomethingAfterStartup() 
    throws Exception {
        
        LOG.info("myEnv (userBucket.path): " + myEnv.getProperty("userBucket.path"));
    }
} 

有3种方法读取application.properties，

使用@Value, EnvironmentInterface和@ConfigurationProperties..

@Value(${userBucket.path})
private String value;

方式2:

@Autowired
private Environment environment;

String s = environment.getProperty("userBucket.path");

第三道:

@ConfigurationProperties("userbucket")
public class config {

private String path;
//getters setters

}

可以读取与getter和setter ..

你可以使用@ConfigurationProperties来访问application.properties中定义的值，这很简单

#datasource
app.datasource.first.jdbc-url=jdbc:mysql://x.x.x.x:3306/ovtools?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
app.datasource.first.username=
app.datasource.first.password=
app.datasource.first.driver-class-name=com.mysql.cj.jdbc.Driver
server.port=8686
spring.jpa.hibernate.ddl-auto=update
spring.jpa.generate-ddl=true
spring.jpa.show-sql=true
spring.jpa.database=mysql

@Slf4j
@Configuration
public class DataSourceConfig {
    @Bean(name = "tracenvDb")
    @Primary
    @ConfigurationProperties(prefix = "app.datasource.first")
    public DataSource mysqlDataSourceanomalie() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "JdbcTemplateenv")
    public JdbcTemplate jdbcTemplateanomalie(@Qualifier("tracenvDb") DataSource datasourcetracenv) {
        return new JdbcTemplate(datasourcetracenv);
    }

应用程序。Yml或application.properties

config.value1: 10
config.value2: 20
config.str: This is a simle str

MyConfig类

@Configuration
@ConfigurationProperties(prefix = "config")
public class MyConfig {
    int value1;
    int value2;
    String str;

    public int getValue1() {
        return value1;
    }

    // Add the rest of getters here...      
    // Values are already mapped in this class. You can access them via getters.
}

任何想要访问配置值的类

@Import(MyConfig.class)
class MyClass {
    private MyConfig myConfig;

    @Autowired
    public MyClass(MyConfig myConfig) {
        this.myConfig = myConfig;
        System.out.println( myConfig.getValue1() );
    }
}
