This was my second time to write blog on CSDN.
This was a maven-webapp project.

I was getting this error.

In short：

 java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger

It was not a serious problem to slove.

You could easily googled and find out that is because of the version of class “slf4j” including class “slf4j-api” and class “slf4j-log4j12”.
Taken examples by:
http://stackoverflow.com/questions/12926899/java-lang-noclassdeffounderror-org-slf4j-loggerfactory
https://yq.aliyun.com/articles/70779

Setting the same version of the above two class was OK.

In my project, it should work:

<dependency>    <groupId>org.slf4j</groupId>    <artifactId>slf4j-api</artifactId>    <version>1.5.8</version></dependency><dependency>    <groupId>org.slf4j</groupId>    <artifactId>slf4j-log4j12</artifactId>    <version>1.5.8</version></dependency>

Find the right version for your project plz.
