Groovlets (groovy servlet) 的 helloword

需要
Groovy Version: 1.5.0
resin pro 3.1.4
groovy的安装，略

启动resin后，会有一个%RESIN_HOME%\webapps\ROOT\WEB-INF\web.xml文件。
增加如下内容

<servlet>
 <servlet-name>GroovyServlet</servlet-name>
 <servlet-class>groovy.servlet.GroovyServlet</servlet-class>
 </servlet>
 <servlet>
 <servlet-name>GroovyTemplate</servlet-name>
 <servlet-class>groovy.servlet.TemplateServlet</servlet-class>
 </servlet>
 <servlet-mapping>
 <servlet-name>GroovyServlet</servlet-name>
 <url-pattern>*.groovy</url-pattern>
 </servlet-mapping>
 <servlet-mapping>
 <servlet-name>GroovyTemplate</servlet-name>
 <url-pattern>*.gsp</url-pattern>
 </servlet-mapping>

copy %GROOVY_HOME%\lib\下的
groovy-1.5.0.jar
asm-2.2.jar
antlr-2.7.6.jar
到
%RESIN_HOME%\lib
启动resin，在
%RESIN_HOME%\webapps\ROOT下新建2个文件
hello.gsp
————-

<%
def h="hello"
def w="world"
println "$h $w"
print 2+2
println " times"
%>

hello.groovy
——-

println """
<html>
 <head>
 <title>Groovy Servlet</title>
 </head>
 <body>
Hello world @ ${new Date()}
 </body>
</html>
"""

运行后
http://localhost:8080/1.gsp
http://localhost:8080/a.groovy
的内容分别为
hello world 4 times
Hello world @ Thu Dec 13 23:04:18 CST 2007
