一次web发布过程的相关配置

keyword: 配置 Tomcat配置 MySql配置 server.conf my.ini 启动参数虚拟机参数 jsp预编译
Author: Alex
发布环境: Tomcat5 + MySql4 +Hibernate + Win2003

一.MySql配置文件
my.ini文件配置

# The default character set that will be used when a new schema or table is
# created and no character set is defined

####设置字符集,MySql默认为 latin1,如果你的存储出现乱码就改为GBK吧
#default-character-set = latin1
default-character-set = GBK

# The default storage engine that will be used when create new tables when

###建议用INNODB,支持事务
default-storage-engine = INNODB

二.Tomcat配置文件

server.conf

主要是配置一个上下文和数据源
相关配置如下:

< Context path ="/sample" docBase =" sample "    debug ="0" privileged ="true" >
             < Resource name ="jdbc/ sample " auth ="Container" type ="javax.sql.DataSource" />
             < ResourceParams name ="jdbc/ sample " >
                 < parameter >
                     < name > username </ name >
                     < value > sample </ value >
                 </ parameter >
                 < parameter >
                     < name > password </ name >
                     < value > sample </ value >
                 </ parameter >
                 < parameter >
                     < name > driverClassName </ name >
                     < value > org.gjt.mm.mysql.Driver </ value >
                 </ parameter >
                 < parameter >
                     < name > url </ name >
                     < value > jdbc:mysql://localhost/ sample </ value >
                 </ parameter >
               </ ResourceParams >
     </ Context >

ps:如果要支持reloadble,代码为:
<Context path="/cpms" docBase="cpms" debug="0" privileged="true" reloadable="false">

记得把jdbc驱动拷贝到Tomcat的common\lib下

优化jvm参数

修改Tomcat的bin目录下的catalina.bat文件

set JAVA_OPTS = -Xms512m -Xmx512m

注:如果你的 Tomcat是通过service方式启动的这个设置不起作用,所以你最好通过startup.bat方式来启动,service 是直接调用Tomcat.exe,所以不知道怎么设置参数,我试了一下在服务里的"启动参数"里加入
-Xms512m -Xmx512m好像不起作用.知道的兄弟补充下啊

好了,启动你的Tomcat吧,查看资源管理器,看内存是否已经被Tomcat占用了512M

三.web.xml配置
主要涉及数据源,servlet,tld映射
web.xml配置如下:

<? xml version="1.0" encoding="UTF-8" ?>

四.hibernate配置文件,hibernate.cfg.xml

<? xml version="1.0" encoding="utf-8" ?>
<! DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd" >

         < mapping resource ="conf/mapping/Sample.hbm.xml" />


     </ session-factory >
</ hibernate-configuration >

五.这个其实不是配置,应该算是一项优化方案,即jsp预编译
jsp预编译有2个好处

提高jsp响应速度,因为jsp全部预先编译成class了,少了中间的环节
增强jsp安全性,你的jsp源码可以全部删除,只提供一个YourJsps.jar包到lib就可以了

在weblogic里预编译非常方便,可以在console里配置通过开关配置这个参数,但是Tomcat就没有这个好事了,不过我们可以手工完成,我找了下资料,在ant里配置如下:

< target name ="jsp2java" >
   < taskdef classname ="org.apache.jasper.JspC" name ="jsp2java" >
    < classpath id ="jsp2java.classpath" >
     < fileset dir ="${tomcat.home}/bin" >
      < include name ="*.jar" />
     </ fileset >
     < fileset dir ="${tomcat.home}/server/lib" >
      < include name ="*.jar" />
     </ fileset >
     < fileset dir ="${tomcat.home}/common/lib" >
      < include name ="*.jar" />
     </ fileset >
    </ classpath >
   </ taskdef >

   < jsp2java classpath ="jsp2java.classpath" javaEncoding ="UTF-8" validateXml ="false" uriroot ="${web.dir}" webXmlFragment ="${web.dir}/WEB-INF/webJSP.xml" outputDir ="${web.dir}/WEB-INF/JspC/src" />
</ target >

< target name ="java2class" >
   < mkdir dir ="${web.dir}/WEB-INF/JspC/classes" />
   < javac srcdir ="${web.dir}/WEB-INF/JspC/src" destdir ="${web.dir}/WEB-INF/JspC/classes" encoding ="UTF-8" optimize ="off" debug ="on" failonerror ="false" excludes ="**/*.smap" >
    < classpath id ="java2class.classpath" >
     < pathelement location ="${web.dir}/WEB-INF/classes" />
     < fileset dir ="${web.dir}/WEB-INF/lib" >
      < include name ="*.jar" />
     </ fileset >
     < pathelement location ="${tomcat.home}/common/classes" />
     < fileset dir ="${tomcat.home}/common/lib" >
      < include name ="*.jar" />
     </ fileset >
     < pathelement location ="${tomcat.home}/shared/classes" />
     < fileset dir ="${tomcat.home}/shared/lib" >
      < include name ="*.jar" />
     </ fileset >
     < fileset dir ="${tomcat.home}/bin" >
      < include name ="*.jar" />
     </ fileset >
    </ classpath >
    < include name ="**" />
    < exclude name ="tags/**" />
   </ javac >
</ target >
< target name ="class2jar" >
   < jar basedir ="${web.dir}/WEB-INF/JspC/classes" jarfile ="${web.dir}/WEB-INF/lib/${project.name}JSP.jar" />
</ target >
< target name ="clear" >
   < delete dir ="${web.dir}/WEB-INF/JspC/classes" />
   < delete dir ="${web.dir}/WEB-INF/JspC/src" />
   < delete dir ="${web.dir}/WEB-INF/JspC" />
</ target >

有一点不是很方便,就是要手工把生成的webJSP.xml的内容拷贝到web.xml中,应该有更方便的办法,比如
在web.xml中引入这个文件.不过我不知道怎么引入.知道的一定要告诉我啊 :)

我试了下,执行jsp2java没有问题,不过java2class则报错,错误如下:

ow_jsp.java: 134 : 无法将 org.apache.jsp.jsp.show_jsp 中的 _jspx_meth_logic_present_2(javax.servlet.js
p.tagext.JspTag , javax.servlet.jsp.PageContext) 应用于 (org.apache.struts.taglib.logic.IterateTag , jav
ax.servlet.jsp.PageContext)
[ javac ] if (_jspx_meth_logic_present_2(_jspx_th_logic_iterate_0 , pageContext))

不知道怎么搞的,该提供的类路径全给了,好像是Struts的标签解析的时候出错了,还有什么地方会出问题呢,过段时间再研究这个问题,知道的兄弟也告知下哦 :)

大致就这些了.

后记:java2class报错原因已经找到,是jar文件冲突出错,我用的是servlet2.3.jar,以前不知从哪下的,后来把tomcat目录下的common\lib下的servlet-api.jar做servlet解析就没问题了
