Java开发思考笔记

一个接口能否同时返回json和html呢？如下返回会不会有冲突？

	@RequestMapping(value="/uploadBackground")
	@LoggerManage(description="上传背景页面")
	public String uploadBackground(){
		return "user/uploadbackground";
	}

答：应该是不能的，目前应该做不到前后端分离，如果是给app写接口建议重新新建一个方法如

@RequestMapping(value="app/uploadBackground")
@LoggerManage(description="上传背景页面")
	public String uploadBackground(){
		return “”
	}

怎么部署javaweb项目？

思路：把自己的电脑当服务器给外网访问
1.打包war https://blog.youkuaiyun.com/lhp3000/article/details/78994010
2.使用花生壳（付费6元） https://blog.youkuaiyun.com/wzl_fight/article/details/78285450?utm_source=blogxgwz3

80端口占用怎么解决？

80端口被System进程占用且该进程不能被结束的情况，解决办法是：打开RegEdit:
找到HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/HTTP
找到一个DWORD值Start，将其改为0
重启电脑，System进程将不会占用80端口

我的是因为apache占用8080造成的，

TomCat如何绑定多个项目

http://www.cnblogs.com/mibloom/p/9461683.html

//主要是对docBase的修改
<Context path=""  docBase="/favorites" reloadable="true" />   

例：如两个项目配置如下

 <Service name="Catalina">
    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
	<Engine name="Catalina" defaultHost="v226522h00.imwork.net">      
      <Realm className="org.apache.catalina.realm.LockOutRealm">       
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
		<Host name="v226522h00.imwork.net"  appBase="webapps"  
				unpackWARs="true" autoDeploy="true">
		<!--项目一 -->						
		<Context path=""  docBase="/favorites" reloadable="true" />     
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
    </Engine>
  </Service>
<Service name="Catalina">
    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
	<Engine name="Catalina" defaultHost="v226522h00.imwork.net">      
      <Realm className="org.apache.catalina.realm.LockOutRealm">       
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
		<Host name="v226522h00.imwork.net"  appBase="webapps"  
				unpackWARs="true" autoDeploy="true">    
		<!--项目二 -->				
		<Context path=""  docBase="/DTM" reloadable="true" />     
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
    </Engine>
  </Service>
