spring - Logback logging not working -


i've spring mvc simple addressbook project build maven. want use logback logging, i'm new it; first changed pom.xml way:

<!-- spring 3 dependencies --> <dependency>   <groupid>org.springframework</groupid>   <artifactid>spring-context</artifactid>   <version>${spring.version}</version>   <exclusions>     <!--exclude commons logging in favor of slf4j-->      <exclusion>       <groupid>commons-logging</groupid>       <artifactid>commons-logging</artifactid>     </exclusion>   </exclusions> </dependency>    <!-- logging --> <dependency>   <groupid>org.slf4j</groupid>   <artifactid>slf4j-api</artifactid>   <version>1.6.1</version> </dependency> <dependency>   <groupid>ch.qos.logback</groupid>   <artifactid>logback-classic</artifactid>   <version>${logback.version}</version> </dependency> <dependency>   <groupid>ch.qos.logback</groupid>   <artifactid>logback-core</artifactid>   <version>${logback.version}</version> </dependency>

then added lines custom exception databaseexception:

private final static logger logger = (logger) loggerfactory.getlogger(databaseexception.class);

...

public databaseexception(throwable cause) {     super(cause);     logger.log(level.warning, cause.getmessage()); }

so when rise in other classes exception log able print stout messages, does't work, when run maven on tomcat prints container log [talledcontainer] info .... etc etc. seems logger doesn't exists

to databaseexception make work, databaseexception should this:

package org.myorg.myapp;  import org.slf4j.logger; import org.slf4j.loggerfactory;  public class databaseexception extends exception {    private final static logger logger = loggerfactory.getlogger(databaseexception.class);    public databaseexception(throwable cause) {     super(cause);     logger.warn(cause.getmessage());   } }

also, need include jcl-over-slf4j dependency in pom.xml.

<dependency>   <groupid>org.slf4j</groupid>   <artifactid>jcl-over-slf4j</artifactid>   <version>1.6.1</version>   <scope>runtime</scope> </dependency>

i recommend reading reference documentation (using slf4j section). http://static.springsource.org/spring/docs/3.2.x/spring-framework-reference/html/overview.html

hope helps.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
