The background object of thymeleaf is null, which solves the problem of error when the object is empty to get the property value

The sale object passed from the background is sale = null

 ${sale.warrantyPeriod}

You will be prompted that warrantyperiod cannot be found. Change it to the following:

 th:value="${sale?.warrantyPeriod}"

If the object is empty, the output is empty; if the object exists, the output property value.

SLF4J: Class path contains multiple SLF4J bindings.

The error is shown in the figure

 
The reason for this error is that there are two bridges when the log information is generated, and the conflict results in error.

The solution is as follows:

Find the structure diagram in the POM file, and press and hold the Cril key to enlarge the diagram

Find the dependency as shown in the figure below, because there are two bridge conflicts, we only need to eliminate one

As shown in the figure below, right-click the logback classic we found and left-click exclude

At this point, our modification is good. Return to our POM file and update our modification, as shown in the following figure:

At this point, we can run our project again and find that our mistakes are gone, as shown in the figure below.

[Solved] The method getContextPath() from the type HttpServletRequest refers to the missing type String

Leave a reply

Error: “The method getContextPath() from the type HttpServletRequest refers to the missing type String”

Solution: See if the project’s jre is different from your local name (the jre version or the name is different will cause this problem).

Specific operation:

    1. Right-click the project-Build Path-Configure Build Path, under the Libraries option, you will find an error jre Libraries, remove it.

    2. Then right-click the project-Build Path-Add Library, select JRE System Library, select Workspace defaulr JRE (jdk1.6) (the JDK has been successfully installed and configured before), and then Finish.

Note: For your own experience, you must also check whether the environment variable configuration is correct, and then restart Eclipse and recompile the program clear.

1. Open My Computer-Properties-Advanced-Environment Variables 

2. New system variables JAVA_HOME and CLASSPATH 
Variable name: JAVA_HOME 
Variable value: C:\Program Files\Java\jdk1.7.0
Variable name: CLASSPATH 
Variable value: .;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;

3. Select the environment variable named "Path" in "System Variables", double-click the variable, add the absolute path of the bin directory in the JDK installation path to the value of the Path variable, and use half-width semicolons and existing The path is separated. 
Variable name: Path 
Variable value: ;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;
This is the java environment configuration. After the configuration is completed, start eclipse directly, it will automatically complete the java environment configuration
