读取并遍历spring所有配置

读取并遍历spring所有配置，包含系统和自定义(yml或者propreites)

@Autowired
private Environment environment;

public void printAllProperties() {
    MutablePropertySources propertySources = ((AbstractEnvironment) environment).getPropertySources();
    for (PropertySource<?> propertySource : propertySources) {
        // 获取当前 PropertySource 的所有属性名
        if (propertySource instanceof EnumerablePropertySource<?>) {
            String[] propertyNames = ((EnumerablePropertySource<?>) propertySource).getPropertyNames();
            for (String propertyName : propertyNames) {
                // 获取属性值
                Object propertyValue = propertySource.getProperty(propertyName);
                System.out.println(propertyName + ": " + propertyValue);
            }
        }
    }
}
