在spring boot中动态生成Application.properties文件

@Component
@ConfigurationProperties(prefix = "dynamic")
public class DynamicProperties {
    private String property1;
    private int property2;
    // 其他属性及其getter和setter方法
}

dynamic.property1=default value
dynamic.property2=0

@Component
public class DynamicPropertiesBeanPostProcessor implements BeanPostProcessor {
    @Autowired
    private DynamicProperties dynamicProperties;

    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
        if (bean instanceof PropertySourcesPlaceholderConfigurer) {
            Properties properties = new Properties();
            properties.setProperty("property1", dynamicProperties.getProperty1());
            properties.setProperty("property2", String.valueOf(dynamicProperties.getProperty2()));
            // 其他属性及其值
            ((PropertySourcesPlaceholderConfigurer) bean).setProperties(properties);
        }
        return bean;
    }
}

@Service
public class MyService {
    @Value("${property1}")
    private String property1;

    @Value("${property2}")
    private int property2;

    // 其他代码
}
