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
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">

</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:
<!-- =================================================================== -->
<!-- precompile jsp -->
<!-- =================================================================== -->
<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
