Recently want to do a simple extjs5 login jump, before doing a, but ExtJS and no jump link, each refresh need to re-login, the implementation of the bad, now want to realize the authentication of the login user, so see the Shiro this framework, it seems to be more useful, so began to study.

Just started to build, found the official website to the Hello World program needs maven support for POM file research and not deep, can only abandon this way. Install their own official reference manual, download the QuickStart file source code, but this is Maven file, will not be used, can only manually create a new file such, run the time reported a lot of errors, ran a long, finally put Hello world to run out, Now share the entire process of creating a program that you can run:

1. New Shirodemo project using Eclipse/myeclipse

2. Create a new Lib folder, add Shiro-all-1.1.0.jar, Slf4j-api-1.7.7.jar, Slf4j-log4j12-1.7.7.jar, Log4j-1.2.16.jar these jar packages.

3.build Path---Config build path adds these jar packages to libraries

4. Create your own package, for example I create a new Com.susheng package and copy the code from Quickstart.java in QuickStart.

5. Add the Shiro.ini and log4j.properties files to the SRC directory.

6. Run the program:

The program runs correctly.

Before encountering the Error list:

1. shiro.ini file not added

Error message: Exception in thread "main" Org.apache.shiro.config.ConfigurationException:java.io.IOException:Resource [ Classpath:shiro.ini] could not being found.

The reason is that the Shiro.ini file is not added, the workaround is to put the Shiro.ini in the SRC directory can be resolved.

2. Self4j-log4j12.jar package not added correctly

Error message: slf4j:failed to load Class "Org.slf4j.impl.StaticLoggerBinder".

SELF4J's package has not been added to complete, this problem really made me depressed for a long time. Look at the instance code, I introduced the Slf4j-api-1.7.7.jar package, can be normal code, no error hint, but incredibly this jar is also dependent on other jar package can be, which makes me uncomfortable ah. The introduction of additional self4j jar packages (Slf4j-log4j12-1.7.7.jar) can be resolved.

3. No jar package with log4j introduced

Error message: Java.lang.noclassdeffounderror:org/apache/log4j/level

4. No log4j configuration file

Error message: Log4j:warn No appenders could is found for logger (org.apache.shiro.io.ResourceUtils).

Add log4j.properties to the SRC directory to resolve the issue.

The final program directory structure is as follows:

The code is Shiro example, also paste a bit of it.
