Question

我将Spring MVC应用程序与Hibernate集成。

我正在尝试使用Log4j记录jdbc SQL语句参数，但它不起作用。看起来我的log4j.properties配置文件没有做任何更改。这是项目配置：

我正在使用Maven，Eclipse和log4j.properties文件位于项目源文件夹的顶部（据我所知在类路径中）。

Answer 1

行。所以我终于搞定了！

所有这些麻烦都是由JBoss AS 7.1引起的。

以下是如何在JBoss AS 7.1上运行的Spring MVC应用程序上设置slf4j + log4j日志：

必须关闭内置的JBoss模块 - 将 jboss-deployment-structure.xml 添加到 META-INF / 目录
您必须在类路径中包含这些库： log4j.jar ， slf4j-api.jar ， slf4j-log4j12.jar ，<强> JCL-过sfl4j.jar 即可。必须从类路径中排除Spring的默认 common-logging.jar 。
您必须在类路径中包含 log4j.properties 或 log4j.xml 文件。

这些文件让我控制了日志，我实现了我的目标 - 记录Hibernate SQL语句参数。

的JBoss部署-structure.xml

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="org.apache.log4j" />
            <module name="org.slf4j" />
            <module name="org.slf4j.impl" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

log4j.properties

log4j.rootLogger=INFO, A1, R

log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.Target=System.out
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE

Answer 2

您在log4j配置中使用此功能

org.apache.commons.digester.Digester=INFO
org.hibernate=INFO
org.springframework.orm=DEBUG,stdout

它应该是

log4j.logger.org.apache.commons.digester.Digester=INFO
log4j.logger.org.hibernate=INFO
log4j.logger.org.springframework.orm=DEBUG,stdout

Answer 3

在hibernate.cfg.xml或persistence.xml：

中尝试使用以下内容

<property name="hibernate.show_sql">true</property>
<property name="hibernate.use_sql_comments">true</property>

在log4j.properties内加上以下内容：

log4j.rootLogger=INFO,stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Threshold=INFO
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{dd/MM/yyyy HH:mm:ss} %-5p %x - %m%n

org.apache.commons.digester.Digester=INFO
org.hibernate=INFO
org.springframework.orm=DEBUG,stdout

如果您将这两个文件放在webapp的类路径中，我毫不怀疑您将拥有日志。

使用Maven，您应该将这些文件放在文件夹src/main/resources中。如果您执行'mvn clean package`，它们将打包在生成的target文件夹中。

要声明slf4j记录器，您应该这样做：

public class User {
    public static final Logger logger = LoggerFactory.getLogger(User.class);

    //fields getters and setters...

    public User() {

    }

    public User(DTO userDTO) {
        this.username = userDTO.username;
        // etc.
        logger.debug("your user was initialized with the DTO, see this.toString()=?", this.toString());
    } 


    //etc. some other methods, if any

    //toString()
    public String toString() {
        //return a String representation of an User object.
    }
}

要限制特定appender的日志级别，您应该使用：

log4j.logger.appenderName.packageName.className=LEVEL

请注意您目前正在使用：

log4j.logger.packageName.className=LEVEL
