背景

前几天，碰到一个SimpleEvaluationContext类找不到的问题：

异常栈如下：

分析

中文资料没找到，于是去google资料，发现是spring-expression版本问题：

我使用的是springboot 1.5.13.RELEASE，eclipse的maven依赖树显示，对应的spring-expression版本是4.3.10.ELEASE。

另一个老外看到的版本跟我不一样，他显示的依赖版本是4.3.14.ELEASE。

最重要的信息来了：

SimpleEvaluationContext was added in 4.3.15.RELEASE so the fact you can't find it in 4.3.14.RELEASE is perfectly normal.
Spring Boot 1.5.13 uses Spring Framework 4.3.17.RELEASE.

由此可见，由于SimpleEvaluationContext 是4.3.15.RELEASE才增加的，只要把依赖的版本大于这个版本就行了。但由于官方推荐springBoot 1.5.13应该使用spring的4.3.17.RELEASE版本，那就把spring版本升级。

官方文档：https://github.com/spring-projects/spring-boot/blob/v1.5.13.RELEASE/spring-boot-dependencies/pom.xml#L154

解决方案

在pom文件中添加

<properties>
...

<spring.version>4.3.17.RELEASE</spring.version>
</properties>

<dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-expression</artifactId>
           <version>4.3.17.RELEASE</version>
       </dependency>

...
