TOMCAT5.0+MYSQL配置JDBC,DBCP,SSL

类别: JSP教程  评论数:0 总得分:0
准备环境:

1.j2sdk-1_4_2-windows-i586.exe

//jdk

2.mysql-4.0.20d-win.zip

//mysql数据库

3.mysqlcc-0.9.4-win32.zip

//mysqlGUI控制

4.jakarta-tomcat-5.0.27.exe

//tomcat服务器

5.mysql-connector-java-3.0.14-production.zip

//内含mysql驱动

安装步骤:

1.安装jdk

2.安装tomcat

3.安装mysql

4.安装mysqlcc

5.将驱动包解压,拷贝mysql-connector-java-3.0.14-production-bin.jar

到tomcat/common/lib下

或者下载mm.mysql-2.0.14-you-must-unjar-me.jar,

解压后拷贝其中的mm.mysql-2.0.14-bin.jar

Tomcat5.0配置 本例使用安装密码 198277

1.配置manager 管理应用程序

在conf/server.xml 中

添加如下:

<Service name="Catalina">
...

<Context path="/manager"
debug="0" privileged="true"
docBase="/usr/local/kinetic
/tomcat5/server/webapps/manager">
</Context>

</Service>



限制IP访问配置

<Context path="/manager"
debug="0" privileged="true"
docBase="/usr/local/kinetic
/tomcat5/server/webapps/manager">
<Valve className="org.apache.
catalina.valves.RemoteAddrValve"
allow="127.0.0.1"/>
</Context>



测试为:http://localhost:8080/manager/html

2、配置JDBCRealm容器管理安全,以mysql-4.0数据库为例

a.拷贝驱动mm.mysql-2.0.14-bin.jar到common/lib/下

b.在数据库ycg中建表

create table users
(
user_name
varchar(15) not null primary key,
user_pass
varchar(15) not null
);

create table user_roles
(
user_name
varchar(15) not null,
role_name
varchar(15) not null,
primary key (user_name, role_name)
);



c.修改server.xml如下(默认数据库为root,无密码,如果有形如:

connectionURL="jdbc:mysql:
//localhost/authority?

user=dbuser&password=dbpass")
<Realm className="org.apache.catalina.
realm.JDBCRealm" debug="99"
driverName="
org.gjt.mm.mysql.Driver"
connectionURL="jdbc:mysql:
//localhost/ycg?user=root"
connectionName=""
connectionPassword=""
userTable="users"
userNameCol="user_name"
userCredCol="user_pass"
userRoleTable="user_roles"
roleNameCol="role_name" />



d.在数据库中添加入tomcat的默认配置数据:



e.启动mysql,启动tomcat,此后tomcat将从数据库中读用户规则认证.默认的conf/tomcat-users.xml失效

3.DBCP的配置

a.设置

<parameter>
<name>removeAbandoned</name>
<value>true</value>
</parameter>



可使失效的数据连接重新启用.

配套设置

<parameter>
<name>removeAbandonedTimeout</name>
<value>60</value>
</parameter>



失效时间

如果要写入日志

设置

<parameter>
<name>logAbandoned</name>
<value>true</value>
</parameter>



以上三个默认都是false

b.以mysql为例,配置数据连接池

c.配置新的用户与数据库,必须设定密码,空密码将导致连接失败

e.

指定root密码:

mysqladmin -u root -h localhost
password "198277"



(需修改上面的jdbcrealm设置connectionURL="jdbc:mysql://localhost/ycg?user=root&password=198277")

命令mysql进入匿名连接到服务器

密码访问

shell> mysql -h host -u user -p
Enter password: ********
//如果root没有密码,以下是不成功的.(试过了)
mysql> GRANT ALL PRIVILEGES ON *.*
TO javauser@localhost
-> IDENTIFIED BY \'javadude\'
WITH GRANT OPTION;
mysql> create database javatest;
mysql> use javatest;
mysql> create table testdata
(
-> id int not null
auto_increment primary key,
-> foo varchar(25),
-> bar int);

在conf/server.xml中<host></host>
中添加
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true"
crossContext="true">

<Logger className="org.apache.
catalina.logger.FileLogger"
prefix="localhost_DBTest_log."
suffix=".txt"
timestamp="true"/>

<Resource name="jdbc/TestDB"
auth="Container"
type="javax.sql.DataSource"/>

<ResourceParams name="jdbc/TestDB">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.
BasicDataSourceFactory</value>
</parameter>

<!-- Maximum number of dB connections
in pool. Make sure you
configure your mysqld
max_connections large enough to handle
all of your db connections.
Set to 0 for no limit.
-->
<parameter>
<name>maxActive</name>
<value>100</value>
</parameter>

<value>30</value>
</parameter>

<!-- Maximum time to wait for a

<value>10000</value>
</parameter>

<!-- MySQL dB username and
password for dB connections -->
<parameter>
<name>username</name>
<value>javauser</value>
</parameter>
<parameter>

-->

<!-- Class name for the official
MySQL Connector/J driver -->
<parameter>
<name>driverClassName</name>
<value>com.mysql.jdbc.Driver</value>
</parameter>

<!-- The JDBC connection url for

-->
<parameter>
<name>url</name>
<value>jdbc:mysql://localhost:3306
/javatest?autoReconnect=true</value>
</parameter>


<parameter>
<name>removeAbandoned</name>
<value>true</value>

<value>60</value>
</parameter>
<parameter>
<name>logAbandoned</name>
<value>true</value>
</parameter>
</ResourceParams>
</Context>



f.在web服务中调用.配置web.xml 如:

<web-app xmlns=
"http://java.sun.com/xml/ns/j2ee"
xmlns:xsi=
"http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=
"http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<description>MySQL Test App</description>
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/TestDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>



g.测试用test.jsp

<%@ taglib uri=
"http://java.sun.com/jsp/jstl/sql"
prefix="sql" %>
<%@ taglib uri=
"http://java.sun.com/jsp/jstl/core"
prefix="c" %>

<sql:query var="rs"
dataSource="jdbc/TestDB">
select id, foo, bar from testdata
</sql:query>

<html>
<head>
<title>DB Test</title>
</head>
<body>

<h2>Results</h2>

<c:forEach var="row" items="${rs.rows}">
Foo ${row.foo}<br/>
Bar ${row.bar}<br/>
</c:forEach>

</body>
</html>



h.新建web应用

下载jakarta-taglibs-standard-1.1.0

copy jstl.jar and standard.jar to your web app\'s WEB-INF/lib

DBTest/
WEB-INF/
web.xml
lib/
jstl.jar
standard.jar
test.jsp



拷贝到webapps/ 下

i.启动mysql,tomcat

访问:

http://localhost:8080/DBTest/test.jsp

显示:

Results
Foo hello
Bar 12345



4.ssl的配置,以jdk1.4.2为例

a.进入%JAVA_HOME%bin

运行命令:keytool -genkey -alias tomcat -keyalg RSA

以tomcat 安装密码为198277,ketool设置密码为198277为例

输入keystore密码: 198277

您的名字与姓氏是什么?

[Unknown]: ycg

您的组织单位名称是什么?

[Unknown]: nju

您的组织名称是什么?

[Unknown]: nju

您所在的城市或区域名称是什么?

[Unknown]: nanjing

您所在的州或省份名称是什么?

[Unknown]: jiangsu

该单位的两字母国家代码是什么

[Unknown]: nd

CN=ycg, OU=nju, O=nju, L=nanjing, ST=jiangsu, C=nd 正确吗?

[否]: y

输入的主密码

(如果和 keystore 密码相同,按回车): 198277

b.在你的D:Documents and Settings的当前用户目录下可以找到.keystore文件.将其拷贝到conf/文件夹下.

c.在server.xml 中找到

<!--
<Connector port="8443"
maxThreads="150" minSpareThreads="25"
maxSpareThreads="75"
enableLookups="false"
disableUploadTimeout="true"
acceptCount="100" debug="0"
scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS" />
-->



去掉注释

添加配置字段:keystoreFile="/conf/.keystore" keystorePass="198277"

如:

<Connector port="8443"
maxThreads="150" minSpareThreads=
"25" maxSpareThreads="75"
enableLookups="false"
disableUploadTimeout="true"
acceptCount="100" debug="0"
scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="/conf/.keystore"
keystorePass="198277"/>



d.测试为:

https://localhost:8443

e.在自己的程序中添加ssl认证方式为:

在web.xml 中添加

<security-constraint>
<web-resource-collection>
<web-resource-name>Success
</web-resource-name>
<url-pattern>/</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL
</transport-guarantee>
</user-data-constraint>
</security-constraint>



f.用上提为例就是

修改web.xml 为

<web-app xmlns=
"http://java.sun.com/xml/ns/j2ee"
xmlns:xsi=
"http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=
"http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">

<description>MySQL Test App</description>

<security-constraint>
<web-resource-collection>
<web-resource-name>Success
</web-resource-name>
<url-pattern>/</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL
</transport-guarantee>
</user-data-constraint>
</security-constraint>


<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/TestDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>



访问:

https://localhost:8443/DBTest/test.jsp

g.如果与2配置的jdbcRealm结合起来进行表单认证

先在user_roles表中添加user_name:ycg role_name:web-user

在users表中添加user_name:ycg user_pass:198277

然后在web.xml中添加

<auth-constraint>
<role-name>web-user</role-name>
</auth-constraint>

<login-config>
<auth-method>BASIC</auth-method>
<realm-name>My Member Area</realm-name>
</login-config>



修改后的web.xml如:

<web-app xmlns=
"http://java.sun.com/xml/ns/j2ee"
xmlns:xsi=
"http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=
"http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">

<description>MySQL Test App</description>

<security-constraint>
<web-resource-collection>
<web-resource-name>Success
</web-resource-name>
<url-pattern>/</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>web-user</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL
</transport-guarantee>
</user-data-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>My Member Area</realm-name>
</login-config>

<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/TestDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>



测试:

http://localhost:8080/DBTest/test.jsp

将通过ssl连接,并进行表单认证.用户密码可在user_roles,和users中添加.

5.中文乱码问题:

mysql 默认编码 iso

tomcat request 传输编码 iso

如果要显示中文

在*.jsp中添加

<head>
<%@ page
language="java"
contentType="text/html;
charset=GB18030"
pageEncoding="GB18030"
%>
</head>



如果是数据传输中的乱码(如用servlet从mysql数据库读出的数据)用以下两个转码函数转码,如果不清楚由哪种编码转成哪种编码,就多尝试。

//转码GBK转ISO
public String toISO(String input)
{
try
{
byte[] bytes = input.getBytes("GBK");
return new String(bytes,"ISO8859-1");
}catch(Exception ex)
{
}
return input;

}

//转码IS0转GBK
public String toGBK(String input)
{
try {
byte[] bytes =
input.getBytes("ISO8859-1");
return new String(bytes,"GBK");
}catch(Exception ex) {
}
return input;
}
