一,建数据库
进入pgAdmin新建一个数据库然后用eclipse的插件ErMaster导出sql或者是自己手写sql新建数据表
,这里新建了一个名为test的数据库Alt text
里面有两个表,member和department,为多对一的关系,注意不要忘了设置主键
二,进入seam目录运行 ./seam setup ./seam create-project ./seam generate
1.运行./seam setup
首先是输入项目需要在哪个目录下生成,可以自己设置 Alt text
然后是设置jboss路径,其它的选项默认就好Alt text
输入项目的名字
Alt text
richfaces的配置,默认就好Alt text
部署方式,选择earAlt text
输入项目的包名,action为home和list的存放目录,model为实体bean,test是一些测试Alt text
下面是数据库的配置,依次输入数据库的名字,驱动jar包目录,往下三项默认,之后是新建的那个数据库的名字,最后是用户名和密码,其余默认即可Alt text

2.运行 ./seam create-project ./seam generate
这些都是全自动的,依次运行就可以

最后不要忘了把MemberList.java中的member改为其它名字,原因是member是postgres的关键字,会发生冲突

<code>    <span>private</span> <span>static</span> <span>final</span> String EJBQL = <span>"select m from Member m"</span>;

    <span>private</span> <span>static</span> <span>final</span> String[] RESTRICTIONS = {
            <span>"lower(m.password) like lower(concat(#{memberList.member.password},'%'))"</span>,
            <span>"lower(m.name) like lower(concat(#{memberList.member.name},'%'))"</span>,
            };</code>
