Description:

A component required a bean named 'requestDao' that could not be found.


Action:

Consider defining a bean named 'requestDao' in your configuration.

查了网上的解决方法，在web.xml中添加

   <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:applicationContext.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

还是没用

最后在Application.java中添加注解：

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class })
@ImportResource(locations = {"classpath:applicationContext.xml" })

再一个是因为application.properties中mongo用户名及密码没有配置，添加配置即可

mongo.replicaSet=localhost:27017
mongo.fixbot.username=root
mongo.fixbot.dbname=mymongo
mongo.fixbot.password=root
