是否有老掉牙的springmvc项目，想转成springboot项目，看这个文章就对了。
说明
如果你的项目连maven项目都不是，请自行转为maven项目，在按照本教程进行。
本教程适用于spring+springmvc+mybatis+shiro的maven项目。
1.修改pom文件依赖
删除之前的spring依赖，添加springboot依赖

2.添加application启动文件
注意，如果Application在controller，service，dao的上一层包里，无需配置 @ComponentScan ,
否则，需要指明要扫描的包。

添加基本配置#默认前缀server.contextPath=/# 指定环境spring.profiles.active=local# jsp配置spring.mvc.view.prefix=/WEB-INF/jsp/spring.mvc.view.suffix=.jsp#log配置文件logging.config=classpath:logback-cms.xml#log路径logging.path=/Users/mac/work-tommy/cms-springboot/logs/#数据源spring.datasource.name=adminDataSourcespring.datasource.driverClassName = com.mysql.jdbc.Driverspring.datasource.url = jdbc:mysql://localhost:3306/mycms?useUnicode=true&autoReconnect=true&characterEncoding=utf-8spring.datasource.username = rootspring.datasource.password = 123456 |
4.使用@Configuration注入配置
注入mybatis配置,分页插件请自主选择

添加Interceptor配置,注意addInterceptor的顺序，不要搞乱了

@Configurationpublic class InterceptorConfigurationextends WebMvcConfigurerAdapter{ @Override public void addInterceptors(InterceptorRegistry registry){ registry.addInterceptor(new LoginHandlerInterceptor()); }} |
添加shiro配置文件
注意：本来使用redis做session缓存，但是和shiro集成发现一个问题，user对象存储以后，从shiro中获取后，无法进行类型转换，所以暂时放弃了redis做session缓存。
