我有与 Hibernate 集成的 Spring MVC 应用程序。

我正在尝试使用 Log4j 记录 jdbc SQL 语句参数，但它不起作用。我的 log4j.properties 配置文件似乎没有做任何更改。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（所以我在类路径中理解）。

好的。所以我终于让它工作了！

所有这些问题都是由 JBoss AS 7.1 造成的。

所以这里是如何在 JBoss AS 7.1 上运行的 Spring MVC 应用程序上设置 slf4j+log4j 日志记录：

  1. 有内置的 JBoss 模块必须关闭所以 - 将jboss-deployment-structure.xml添加到您的META-INF/目录
  2. 您必须在类路径中有这些库：log4j.jar、slf4j-api.jar、slf4j-log4j12.jar、jcl-over-sfl4j.jar。Spring 的默认common-logging.jar必须从类路径中排除。
  3. 您必须在类路径中有log4j.properties或log4j.xml文件。

这些文件让我可以控制日志，我实现了我的目标——记录 Hibernate SQL 语句参数。

jboss-部署-结构.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>

您在 log4j 配置中使用它

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

而它应该是

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

hibernate.cfg.xml在您的或您的中尝试以下内容persistence.xml：

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

加上您的以下内容log4j.properties：

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

如果你把这两个文件放在你的 webapp 的类路径中，我毫不怀疑你会有日志。

使用 Maven，您应该将这些文件放在文件夹src/main/resources中。target如果您执行“mvn clean package”，它们将被打包在您将获得的结果文件夹中。

要声明一个 slf4j 记录器，你应该这样做：

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.
    }
}

要限制特定附加程序的日志级别，您应该使用：

log4j.logger.appenderName.packageName.className=LEVEL

请注意，您当前正在使用：

log4j.logger.packageName.className=LEVEL

祝你好运！
