java - Spring Boot 忽略来自外部 application.properties 的日志记录级别

Question

我正在 Tomcat 上运行打包在 war 文件中的 Spring Boot(版本 1.5.2.RELEASE)应用程序。在我的上下文文件 (conf/Catalina/localhost/ROOT.xml) 中，我指定了外部属性文件的路径，如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<Context>
    <Environment name="spring.config.location" value="file:/opt/shared/home/.airlines-data/" type="java.lang.String"/>
</Context>

在路径 /opt/shared/home/.airlines-data/ 中，我有一个带有以下行的 application.properties 文件:

logging.level.root=WARN
logging.level.org.hibernate=ERROR
logging.level.org.springframework.web=WARN
spring.jpa.properties.hibernate.show_sql=false
spring.jpa.show-sql=false
logging.file=/opt/shared/home/.airlines-data/Errors.log

文件被正确读取。属性 logging.file=/opt/shared/home/.airlines-data/Errors.log 也被正确加载，如果我将其值更改为其他值，一切都会按预期工作。不幸的是，Spring Boot 忽略了所有的日志级别设置。它记录 INFO 级别及更高级别的所有内容。 Hibernate 还将其所有查询记录到日志文件中。这使得日志文件在短时间内变得非常大。有没有其他方法可以将日志记录级别更改为 WARN 或 ERROR 并使用外部配置禁用 Hibernate SQL 日志记录？我正在使用 Spring Boot 提供的标准日志记录设置。以下是我的依赖项:

dependencies {
    compile('org.springframework.boot:spring-boot-starter-jdbc')
    compile('org.springframework.boot:spring-boot-starter-jooq')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.liquibase:liquibase-core')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-mail')
    compile("org.springframework:spring-messaging")
    compile('org.apache.commons:commons-lang3:3.4')
    compile('commons-io:commons-io:2.4')
    compile('commons-beanutils:commons-beanutils:1.9.2')
    compile('com.samaxes.filter:cachefilter:2.3.1')
    compile('com.monitorjbl:xlsx-streamer:0.2.12')
    compile('org.apache.commons:commons-csv:1.2')
    compile('org.imgscalr:imgscalr-lib:4.2')
    compile('xerces:xercesImpl:2.11.0')
    compile('com.fasterxml.jackson.datatype:jackson-datatype-hibernate4:2.6.4')
    compile('org.thymeleaf.extras:thymeleaf-extras-springsecurity4:2.1.2.RELEASE')
    compile('org.jodd:jodd-mail:3.7.1')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test') 
}

我的 Error.log 文件很快就填满了，并且包含很多类似的行:

2017-02-17 18:45:13.338 DEBUG 5168 --- [localhost-startStop-1] o.s.boot.SpringApplication               : Loading source class pl.eb2b.AirlinesApplication,class org.springframework.boot.context.web.ErrorPageFilter

我也试过将 logback-spring.xml 文件放在我的类路径中:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <root level="WARN">
        <appender-ref ref="CONSOLE" />
        <appender-ref ref="FILE" />
    </root>
    <logger name="org.hibernate" level="ERROR" additivity="false">
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE"/>
    </logger>
</configuration>

它在我的本地机器上工作，但在服务器上被忽略了。

我在 catalina.out 日志中发现了一些附加信息，其中包含打印到控制台的所有内容(也许会有帮助):

由于我的服务器是基于 Jelastic 的云服务器，所以它会自动使用这些参数进行配置。不知道有没有关系，但是param -Djava.util.logging.config.file=/opt/repo/versions/8.5.3/conf/logging.properties 看起来像与日志记录有关。以下是该文件的内容:

handlers = 1catalina.org.apache.juli.AsyncFileHandler, 2localhost.org.apache.juli.AsyncFileHandler, 3manager.org.apache.juli.AsyncFileHandler, 4host-manager.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler

.handlers = 1catalina.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler

1catalina.org.apache.juli.AsyncFileHandler.level = FINE
1catalina.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.AsyncFileHandler.prefix = catalina.

2localhost.org.apache.juli.AsyncFileHandler.level = FINE
2localhost.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs

我们能够找到的一些文章(1、2)说了以下内容:

Default Logging Support in Spring Boot

Spring Boot reference document says:

By default, If you use the ‘Starter POMs’, Logback will be used for logging. Appropriate Logback routing is also included to ensure that dependent libraries that use Java Util Logging, Commons Logging, Log4J or SLF4J will all work correctly.

因此，您可以在 application.properties 文件中调整 SpringBoot 的日志记录级别，最有可能通过以下路径:

cat /opt/tomcat/webapps/ROOT/WEB-INF/classes/application.properties
logging.level.*=OFF
logging.level.org.springframework.web=WARN
logging.level.org.springframework.boot=OFF
logging.level.org.hibernate.SQL=OFF

更改完成后，调试消息应该从 catalina.out 中消失
