Jboss部署时Jackson相关包的错误
迫于公司规定..一定要用jboss部署war包。众所周知，springboot本就是用来简化配置适合轻量级的容器的，然而....
所以，结果就是今天部署admin的时候又出现了问题..
明明都是正常的服务...
状态却显示都是Unknown
使用tomcat启动缺没有任何问题，都可以正常显示
查看jboss启动日志发现

居然找不到Jackson的这个方法，查找jar包显然有这个方法，这时候经验告诉我是jar包冲突了
由于jboss的module中自带Jackson而且版本较低，无法和Springboot2.x之后的兼容，因此需要在项目文件WEB-INF中添加jboss-deployment-structure.xml
<?xml version="1.0" encoding="UTF-8" ?> <jboss-deployment-structure> <deployment> <exclusions> <module name="com.fasterxml.jackson.core.jackson-core" /> <module name="com.fasterxml.jackson.core.jackson-annotations" /> <module name="com.fasterxml.jackson.core.jackson-databind" /> <module name="com.fasterxml.jackson.datatype.jackson-datatype-jdk8" /> <module name="com.fasterxml.jackson.datatype.jackson-datatype-jsr310" /> <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" /> <module name="org.jboss.resteasy.resteasy-jackson2-provider" /> <module name="org.jboss.resteasy.resteasy-jackson-provider" /> </exclusions> </deployment> </jboss-deployment-structure>
所有相关Jackson的包都要去除，不然可能会有其他错误
