SpringBoot 项目启动报错：

第一次启动报错：

Caused by: java.lang.NoSuchMethodError: freemarker.template.Configuration.<init>(Lfreemarker/template/Version;)V
	at org.springframework.ui.freemarker.FreeMarkerConfigurationFactory.newConfiguration(FreeMarkerConfigurationFactory.java:328)
	at org.springframework.ui.freemarker.FreeMarkerConfigurationFactory.createConfiguration(FreeMarkerConfigurationFactory.java:258)
	at org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer.afterPropertiesSet(FreeMarkerConfigurer.java:120)

	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1704)

第二次启动报错：

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method freemarker.template.Configuration.<init>(Lfreemarker/template/Version;)V but it does not exist. Its class, freemarker.template.Configuration, is available from the following locations:

    jar:file:/C:/Users/javam/.m2/repository/org/freemarker/freemarker/2.3.20/freemarker-2.3.20.jar!/freemarker/template/Configuration.class

It was loaded from the following location:

    file:/C:/Users/javam/.m2/repository/org/freemarker/freemarker/2.3.20/freemarker-2.3.20.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of freemarker.template.Configuration

由报错提示信息可知，加载 freemarker.jar 包 <init> 时没有发现。

解决方案：更换 jar 版本。

<dependency>
	<groupId>org.freemarker</groupId>
	<artifactId>freemarker</artifactId>
	<version>2.3.20</version>
</dependency>

修改为：

<dependency>
	<groupId>org.freemarker</groupId>
	<artifactId>freemarker</artifactId>
	<version>2.3.28</version>
</dependency>

项目启动正常！
