如何让Jetty打印日志
我的项目运行在 Wicket+Spring+JPA/Hibernate 上。当我使用以下命令运行它时：
mvn jetty:run
我希望 jetty 打印我在代码中生成的日志。例如，我实现了以下 DAO：
@Repository(value = "isinDao")
public class IsinDaoJpa implements IsinDao {
@PersistenceContext
private EntityManager em;
private static Logger logger = LoggerFactory.getLogger(IsinDaoJpa.class);
public Isin findById(Long id) {
return em.find(Isin.class, id);
}
public List findAll() {
Query query = em.createQuery("select e from Isin e");
logger.info("DAO: All ISINs selected");
return query.getResultList();
}
}
How do I make Jetty print this information real-time into the command line window?
在 pom.xml 中，我有以下依赖项：
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.4.2</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.14</version>
</dependency>
My project runs on Wicket+Spring+JPA/Hibernate. When I run it using the command:
mvn jetty:run
I'd like jetty to print logs I make in the code. I have for example the following DAO implemented:
@Repository(value = "isinDao")
public class IsinDaoJpa implements IsinDao {
@PersistenceContext
private EntityManager em;
private static Logger logger = LoggerFactory.getLogger(IsinDaoJpa.class);
public Isin findById(Long id) {
return em.find(Isin.class, id);
}
public List findAll() {
Query query = em.createQuery("select e from Isin e");
logger.info("DAO: All ISINs selected");
return query.getResultList();
}
}

In pom.xml, I have the following dependencies:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.4.2</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.14</version>
</dependency>

由于您使用 SLF4-to-log4j 桥接器，因此需要在 log4j 配置中配置日志记录。
要使用 Spring 配置 log4j 日志记录，您需要将以下内容添加到
web.xml（在ContextLoaderListener之前）：然后在
/WEB-INF/log4j.xml 中配置 log4j（您也可以使用传统的log4j.properties）：另请参阅：
Since you use SLF4-to-log4j bridge, you need to configure logging in log4j configuration.
To configure log4j logging with Spring you need to add the following to
web.xml(beforeContextLoaderListener):Then configure log4j in
/WEB-INF/log4j.xml(you may also use traditionallog4j.properties):See also:
