 *  场景：  
    在看谷粒商城p20章节视频的时候，我这边本地的springboot版本是`2.5.0`，spring cloud版本是`2020.0.3`。  
    视频里面用的是比较旧的版本，我这边没按视频里面的。  
    在添加完spring cloud依赖，然后加上nacos，进行启动的时候，报错如上信息。
 *  查看项目引入了哪些依赖  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3MxNDQxMTAxMjY1_size_16_color_FFFFFF_t_70]  
    查看的时候有一个和报错信息非常类似，我尝试把它去掉，但是去掉的话，代码就报错了，所以目前不行。  
    然后nacos依赖去掉，尝试启动，就成功了。说明，问题出在nacos依赖上面。
 *  寻找冲突的jar包  
    要找冲突的是哪个jar包，首先，点击项目打开依赖关系  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3MxNDQxMTAxMjY1_size_16_color_FFFFFF_t_70 1]  
    经过放大，找到最低下的这层分支，我们引入的这个依赖  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3MxNDQxMTAxMjY1_size_16_color_FFFFFF_t_70 2]  
    然后看它的下流分支，如果有报红色，那就是说明有冲突。  
    接着，找到错误信息里面相关的依赖  
    httpclient  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3MxNDQxMTAxMjY1_size_16_color_FFFFFF_t_70 3]  
    错误信息里面报的这个类的名称，和这个依赖的名称一样，现在对它右键点击，exclude排除掉试试  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3MxNDQxMTAxMjY1_size_16_color_FFFFFF_t_70 4]  
    启动成功，说明就是它的原因。  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3MxNDQxMTAxMjY1_size_16_color_FFFFFF_t_70 5]

> `分析原因`

这里看图可以知道，原因就是在开始写代码的时候，引入的这个依赖和后面nacos里面的冲突了，同时存在了两个，所以会这样。那么下面想办法把结构梳理下就成了。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3MxNDQxMTAxMjY1_size_16_color_FFFFFF_t_70 6]

> `拓展`

个别无法直接右键排除的依赖，这时候可以鼠标左键点进去，然后复制当前依赖信息，接着在需要排除的依赖下面添加上去
