Introduce freemaker error, java.lang.NoSuchMethodError: freemarker.template.Configuration

An error was reported when the spring project introduced the freemaker view parser:

 The imported jar packages are as follows:

		<!-- freemarker begin -->
		<dependency>
			<groupId>org.freemarker</groupId>
			<artifactId>freemarker</artifactId>
			<version>2.3.20</version>
		</dependency>

 

There is no problem in viewing various configurations, and there is no jar package introduced.

 

Reason: The introduced freemaker version is not compatible with the spring version

 

Solution: Introduce a compatible version of freemaker

 

For example: I am using spring version 5.0.0.M2, then modify the freemaker version to:

		<dependency>
			<groupId>org.freemarker</groupId>
			<artifactId>freemarker</artifactId>
			<version>2.3.27-incubating</version>
		</dependency>
