springboot中用Environment读取自定义配置文件的属性

在Spring Boot中,你可以通过`@ConfigurationProperties`注解以及`Environment`对象来读取自定义配置文件的属性。首先,你需要创建一个Java配置类,并将需要的属性声明为`@Value`或`@ConfigurationProperties(prefix = "your-config-prefix")`。例如:
```java
@Configuration
@ConfigurationProperties(prefix = "custom.config")
public class CustomConfig {
private String property1;
private int property2;
// getters and setters
public String getProperty1() {
return property1;
}
public void setProperty1(String property1) {
this.property1 = property1;
}
public int getProperty2() {
return property2;
}
public void setProperty2(int property2) {
this.property2 = property2;
}
}
```
然后,在启动类或某个需要这些配置的地方,你可以注入这个`CustomConfig`实例并直接访问它的属性:
```java
@Autowired
private CustomConfig customConfig;
public void someMethod() {
String value1 = customConfig.getProperty1();
int value2 = customConfig.getProperty2();
}
```
要在应用运行时动态地从`Environment`中获取配置,可以使用`getProperty()`方法:
```java
String configValue = applicationContext.getEnvironment().getProperty("custom.config.property1");
```
