今日完成：
补全脑图
今天刚开始任务二，先建了个web项目。
下载tomcat并配置环境变量。
springmvc.xml文件需要的内容：
<!-- 配置扫描的包 -->
<context:component-scan base-package="TestJson"/>
<!-- 访问静态资源-->
<mvc:default-servlet-handler />
<!-- 注册映射类 -->
<mvc:annotation-driven />
<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<!-- 后缀 -->
<property name="suffix" value=".jsp" />
</bean>
</beans>
web.xml文件：
<!--配置监听器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<!--拦截规则-->
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

安照教程已经跑通了Hello World，但后面tomcat出了问题，解决不掉。
查看tomcat日志
9月 10, 2018 10:24:59 下午 org.apache.catalina.core.StandardContext startInternal
严重: One or more listeners failed to start. Full details will be found in the appropriate container log file
9月 10, 2018 10:24:59 下午 org.apache.catalina.core.StandardContext startInternal
严重: Context [] startup failed due to previous errors
9月 10, 2018 10:24:59 下午 org.springframework.web.context.support.XmlWebApplicationContext doClose
信息: Closing Root WebApplicationContext: startup date [Mon Sep 10 22:24:59 CST 2018]; root of context hierarchy
9月 10, 2018 10:24:59 下午 org.springframework.web.context.support.XmlWebApplicationContext doClose
警告: Exception thrown from LifecycleProcessor on context close
java.lang.IllegalStateException: LifecycleProcessor not initialized - call 'refresh' before invoking lifecycle methods via the context: Root WebApplicationContext: startup date [Mon Sep 10 22:24:59 CST 2018]; root of context hierarchy
也没找到解决的办法。
整了个静态页面html：
<html>
<head>
<title>Input Information</title>
</head>
<body>
<h3>Input Your Information<h3>
<form name="form1" method="GET" action="JSPhandle.jsp">
NAME:<input type=text name="NAME"><br>
SEX: <select name="SEX">
<option value="1" selected>MALE</option>
<option value="2">FEMALE</option>
</select><br>
<input type="submit" name="SUBMIT" value="submit">
<input type="reset" name="RESET" value="reset">
</form>
</body>
</html>
明日计划：
实在不行就得重装tomcat了
遇到的问题：
感觉对还是对web项目的一些基本流程没有搞清，出了错也不知道该怎么解决了，照着教程搞了一天都不知道自己在干什么。还是得慢慢来，步子大了容易扯到蛋。
