3、遇到的问题
- 3.1、配置spring.xml时头文件出现 cvc-elt.1: Cannot find the declaration of element 'beans'. 报错信息，
eg : http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd - 3.2、利用mybatis-generator自动生成代码，发生：Plugin execution not covered by lifecycle configuration 报错
- 3.1、配置spring.xml时头文件出现 cvc-elt.1: Cannot find the declaration of element 'beans'. 报错信息，

4、解决问题
- 4.1、解决配置文件报错，在pom中找到自己对应配置的spring相关包版本信息，在spring.xml的头文件中，把对应的地址改为和版本号一致的内容
eg : http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.14.xsd - 4.2、解决方案，在plugins标签的上级添加 pluginManagement标签
- 4.1、解决配置文件报错，在pom中找到自己对应配置的spring相关包版本信息，在spring.xml的头文件中，把对应的地址改为和版本号一致的内容
