Log4j:warn no appenders could is found for logger. Console cannot output SQL

The following error occurred while running the Java Project project several days ago:

　　　　

1. First see if the file name is: Log4j.properties or log4j.xml.

2. After confirming that the file location is correct, Java project needs to place the file in: Project/src/or project/Custom folder/. Put it in the top-level directory,

Web Projiect need to put files in the \web-inf\classes folder.

3. If there is no error, it is only to see if the file itself is wrong.

The Java project configuration is as follows:

# Global Logging Configuration
#\u5728\u5f00\u53d1\u73af\u5883\u4e0b\u65e5\u5fd7\u7ea7\u522b\u8981\u8bbe\u7f6e\u6210debug\uff0c\u751f\u4ea7\ U73af\u5883\u8bbe\u7f6e\u6210info\u6216error

Log4j.appender.stdout.layout=org.apache.log4j.patternlayout
log4j.appender.stdout.layout.conversionpattern=%5p [%t]-%m%n

The Web project is configured as follows:

<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/config/log4j.properties</param-value>
</context-param>

This article is to see a number of Bo Friends of the blog summary of the solution, if there are other solutions, hope to share a bit! After solving this problem, SQL can also output from the console:
