Question

我正在构建一个gradle插件，我想让用户能够覆盖外部文件中的某些属性。我正在使用Spring propertyPlaceholderConfigurer来设置用户可以放置文件的几个目的地，这可以按预期工作。我的问题是，在运行我的插件时，Spring打印到控制台：“无法从URL [...]加载属性” 有谁知道如何压制这条消息？

我已经尝试重写logback和sl4j无济于事。

My Spring application-context xml：

<?xml version="1.0" encoding="UTF-8"?>

    <property name="placeholderPrefix" value="${"/>
    <property name="ignoreResourceNotFound" value="true"/>
    <property name="systemPropertiesMode" value="2"/>
</bean>

Answer 1

如果要实现自定义逻辑来设置位置，可以像

一样扩展PropertyPlaceholderConfigurer

class CustomPropertyPlaceholderConfigurer extends org.springframework.beans.factory.config.PropertyPlaceholderConfigurer {

    public void setFileName(String fileName) throws FileNotFoundException {
        File file = findPropertyFile(fileName);  // implement property file loading
        super.setLocation(new FileSystemResource(file));
    }

并像

一样使用它

<bean id="propertyPlaceholderConfigurer" class="package.CustomPropertyPlaceholderConfigurer ">
    <property name="placeholderPrefix" value="${"/>
    <property name="ignoreResourceNotFound" value="true"/>
    <property name="systemPropertiesMode" value="2"/>
</bean>

Answer 2

据我所知，没有这样的文件。

尝试在propertyPlaceholderConfigurer

下面添加配置

<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="ignoreResourceNotFound" value="true" />

Answer 3

我发现该消息源自PropertiesLoaderSupport 在loadProperties方法：

if (this.ignoreResourceNotFound) {
                    if (logger.isWarnEnabled()) {
                        logger.warn("Could not load properties from " + location + ": " + ex.getMessage());
                    }
                }

所以我最终做的是将我的gradle任务中的记录器级别设置为Error，如下所示：

task.doFirst {
    logger.context.level = LogLevel.ERROR
    logging.captureStandardOutput LogLevel.ERROR
}

Spring删除打印输出无法从URL加载属性
