需要使用java实现一个http接口，同事推荐我使用SpringBoot。我使用的是开发环境是eclipse Oxygen.2 Release (4.7.2)，jdk 1.8（64位），按照[eclipse中创建springboot项目（maven）][eclipse_springboot_maven]来创建工程项目。开始很顺利，编译通过，等运行时出现了java.lang.IllegalArgumentException: Sources must not be empty的错误，具体如下图：

![aHR0cHM6Ly9pbWctYmJzLmNzZG4ubmV0L3VwbG9hZC8yMDE5MDgvMDgvMTU2NTI1NzYzMl80ODkxNzMucG5n][]

出错信息如下：

![aHR0cHM6Ly9pbWctYmJzLmNzZG4ubmV0L3VwbG9hZC8yMDE5MDgvMDgvMTU2NTI1NzY0OF8xOTg4NzEucG5n][]

然后我就开始我的折腾之旅了。上网搜了下开始以为了SpringBoot的版本有点低，在pom.xml中将SpringBoot从1.5.2.RELEASE改为1.5.9.RELEASE，然后使用maven更新工程，运行后依然出现一样的问题。再接着准备下载一个SpringBoot的专用开发工具STS，发现这个工具不支持Oxygen.2 Release (4.7.2)，然后就去下载Eclipse最新版4.12。现在下来更新插件时发现qiang太厉害了，把maven的官网都堵住了，然后就想到把maven的更新源改为阿里云，具体是新建一个settings.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
     
    
     
    
    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
      
      <localRepository>D:\Software\DevTools\m2\repository</localRepository> 
      
     
      
     
      
      <pluginGroups>
        
      </pluginGroups>
     
      
      <proxies>
        
      </proxies>
     
      
      <servers>
        
     
        
      </servers>
     
      
      <mirrors>
        
    	 
        <mirror>
          <id>alimaven</id>
          <name>aliyun maven</name>
          <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
          <mirrorOf>central</mirrorOf>        
        </mirror>
         
      </mirrors>
     
      
      <profiles>
        
     
        
      </profiles>
     
      
    </settings>

然后在选择”Window”——”Preferences”进行设置，如下图：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NsZXZlcjEwMQ_size_16_color_FFFFFF_t_70][]

借助这个eclipse的插件更新了，然后再更新工程编译运行，启动项目时报错：

org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

查了一下资料，解决办法是加上@EnableAutoConfiguration注解，具体参考：[关于spring boot org.springframework.context.ApplicationContextException:Unable to start Embedded解决方案][spring boot org.springframework.context.ApplicationContextException_Unable to start Embedded]。

然后再编译运行，出现一个新错误：

org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is java.lang.NoSuchMethodError: org.apache.catalina.Context.addServletMapping(Ljava/lang/String;Ljava/lang/String;)V

再将SpringBoot从1.5.2.RELEASE改为1.5.9.RELEASE，依然一样的错误。到网上搜了一条信息：

[Caused by: java.lang.NoSuchMethodError: org.apache.catalina.Context.addServletMapping(Ljava/lang/Str][Caused by_ java.lang.NoSuchMethodError_ org.apache.catalina.Context.addServletMapping_Ljava_lang_Str]

将SpringBoot从1.5.9.RELEASE再改为2.0.2.RELEASE，然后用maven更新工程，编译运行，这下终于好了。

不过我还有一些疑问：我最新建立的工程在我的一个朋友的机器上是能正常运行的，到底是什么原因造成了这个错误呢？
