网上都说是jar包冲突,就打算通过idea的dependents 打开那个密集的maven依赖图,寻找蛛丝马迹。
结果,直接劝退了,太复杂;
17:22:00.943 [main] ERROR org.springframework.boot.SpringApplication - Application run failed java.lang.NoSuchMethodError: org.yaml.snakeyaml.nodes.ScalarNode.getScalarStyle()Lorg/yaml/snakeyaml/DumperOptions$ScalarStyle; at org.springframework.boot.env.OriginTrackedYamlLoader$KeyScalarNode.<init>(OriginTrackedYamlLoader.java:124) at org.springframework.boot.env.OriginTrackedYamlLoader$KeyScalarNode.get(OriginTrackedYamlLoader.java:135) at org.springframework.boot.env.OriginTrackedYamlLoader$KeyScalarNode.get(OriginTrackedYamlLoader.java:130) at java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:193) at java.util.ArrayList$ArrayListSpliterator.forEachRemaining(ArrayList.java:1374) at java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:481) at java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:471) at java.util.stream.ReduceOps$ReduceOp.evaluateSequential(ReduceOps.java:708) at java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:234) at java.util.stream.ReferencePipeline.collect(ReferencePipeline.java:499)
后来,通过点击控制台错误提示中的代码链接,直接让选择去那个jar包里看代码,立即就找到了是那两个jar包再搞事情。
发现是
selenium-server-standalone-3.141.59.jar 这个里面的jar 和Springboot 中的核心包出现冲突;
这个还是在vue的node_modules里
/Users/大爷/StudioProjects/mogu_blog_v2/vue_mogu_web/node_modules/selenium-server/lib/runner/selenium-server-standalone-3.141.59.jar
先删了再说,后台和前端在一个modle里真不行;
