MySQL Preparation environment:
1.j2sdk-1_4_2-windows-i586.exe
Jdk
2.mysql-4.0.20d-win.zip
MySQL Database
3.mysqlcc-0.9.4-win32.zip
Mysqlgui Control
4.jakarta-tomcat-5.0.27.exe
Tomcat Server
5.mysql-connector-java-3.0.14-production.zip
Contains MySQL driver
Installation steps:
1. Install JDK
2. Install Tomcat
3. Install MySQL
4. Install MYSQLCC
5. Unzip the drive pack and copy the Mysql-connector-java-3.0.14-production-bin.jar
Under the Tomcat/common/lib
or download Mm.mysql-2.0.14-you-must-unjar-me.jar,
Copy the Mm.mysql-2.0.14-bin.jar after decompression
Tomcat5.0 Configuration This example uses the install password 198277
1. Configuring the Manager management application
In the Conf/server.xml
Add the following:
<service name= "Catalina" .... <context path= "/manager" debug= "0" privileged= "true" docbase= "/usr/local/kinetic /tomcat5/server/ Webapps/manager "> </Context></Service>
|
Restricting IP access configuration
<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>
|
Test as: http://localhost:8080/manager/html
2, configure Jdbcrealm container management security, take the mysql-4.0 database as an example
A. Copy drive Mm.mysql-2.0.14-bin.jar to common/lib/
B. Building tables in the database YCG
CREATE TABLE Users ( user_name varchar NOT NULL primary key, user_pass varchar () not NULL); Table User_roles ( user_name varchar () NOT NULL, role_name varchar () NOT NULL, primary Key (user_name, role_name));
|
C. Modify Server.xml as follows (default database is root, no password, if visible as:
Connectionurl= "Jdbc:mysql://localhost/authority?user=dbuser&password=dbpass") <Realm className= "Org.apache.catalina. Realm. Jdbcrealm "debug=" " 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. Add the default configuration data for Tomcat to the database:
E. Start MySQL, start Tomcat, then Tomcat will read the user rule authentication from the database. Default Conf/tomcat-users.xml Expiration
3.DBCP of configuration
A. Set up
<parameter> <name>removeAbandoned</name> <value>true</value> </ Parameter>
|
Enables the disabled data connection to be re-enabled.
Matching settings
<parameter> <name>removeAbandonedTimeout</name> <value>60</value> </parameter>
|
Expiration time
If you want to write to the log
Set up
<parameter> <name>logAbandoned</name> <value>true</value> </ Parameter>
|
All three of the above defaults are false
B. Using MySQL as an example, configure the data connection pool
C. Configure a new user and database, you must set a password, a blank password will cause the connection to fail
E.
Specify root password:
mysqladmin-u root-h localhost password "198277"
|
(need to modify the above Jdbcrealm settings connectionurl= "jdbc:mysql://localhost/ycg?user=root&password=198277")
Command MySQL to enter anonymous connection to server
Password access
shell> mysql-h host-u user-penter Password: ********//If Root does not have a password, the following is unsuccessful. (tried) mysql> GRANT all privileges in *.* to Javauser@localhost-> identified by ' Javadude ' with GRANT OPTION; Mysql> CREATE DATABASE javatest;mysql> use javatest;mysql> CREATE TABLE testdata (-> ID int not NULL AUT O_increment primary KEY,-> foo varchar,-> bar int); add to |
F. Calling in Web services. Configure web.xml such as:
<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/j2eehttp://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. test.jsp for testing
<%@ 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> |
H. Creating a new Web application
Download 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
|
Copy to webapps/
I. Start Mysql,tomcat
Access:
http://localhost:8080/DBTest/test.jsp
Show:
Resultsfoo HelloBar 12345
|
4.ssl configuration, taking jdk1.4.2 as an example
A. Entering the%java_home%\bin
Run command: Keytool-genkey-alias tomcat-keyalg RSA
Set the password to 198277,ketool with the Tomcat installation password of 198277 for example
Enter KeyStore Password: 198277
What is your first and last name?
[Unknown]: YCG
What is your organizational unit name?
[Unknown]: Nju
What is your organization's name?
[Unknown]: Nju
What is the name of your city or region?
[Unknown]: Nanjing
What is the name of your state or province?
[Unknown]: Jiangsu
What is the two-letter country code for that unit?
[Unknown]: ND
CN=YCG, Ou=nju, O=nju, l=nanjing, St=jiangsu, right?
[No]: Y
Input The master password
(press ENTER if same as KeyStore password): 198277
B. keystore files can be found in the current user directory of your D:\Documents and Settings\. Copy it to the conf/folder.
C. Found in the Server.xml
<!-- <connector port= "8443" maxthreads= "minsparethreads= " "maxsparethreads=" Enablelookups= "false" disableuploadtimeout= "true" acceptcount= "debug=" 0 "scheme=" https " Secure= "true" clientauth= "false" sslprotocol= "TLS"/> -->
|
Remove comments
Add Configuration field: keystorefile= "/conf/.keystore" keystorepass= "198277"
Such as:
<connector port= "8443" maxthreads= "minsparethreads=" "maxsparethreads=" "enablelookups=" false " disableuploadtimeout=" true " acceptcount=" debug= "0" scheme= "https" secure= "true" Clientauth= "false" sslprotocol= "TLS" keystorefile= "/conf/.keystore" keystorepass= "198277"/>
|
D. Testing as:
https://localhost:8443
E. Add SSL authentication in your own program as follows:
In the Web.xml Add to
<security-constraint><web-resource-collection><web-resource-name>success</ web-resource-name><url-pattern>/</url-pattern> |
F. The example of using a reference is
Modify Web.xml to
<web-app xmlns= "Http://java.sun.com/xml/ns/j2ee" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" Xsi:sch emalocation= "http://java.sun.com/xml/ns/j2eehttp://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version= "2.4" > & Lt;description>mysql Test app</description><security-constraint><web-resource-collection> <web-resource-name>Success</web-resource-name><url-pattern>/</url-pattern>< Http-method>get |
Access:
https://localhost:8443/DBTest/test.jsp
G. If the Jdbcrealm is combined with the 2 configuration to form authentication
Add USER_NAME:YCG to the User_roles table first Role_name:web-user
Add USER_NAME:YCG user_pass:198277 to the Users table
Then add the Web.xml in the
<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 >
|
Modified Web.xml such as:
<web-app xmlns= "Http://java.sun.com/xml/ns/j2ee" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" Xsi:sch emalocation= "http://java.sun.com/xml/ns/j2eehttp://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version= "2.4" > & Lt;description>mysql Test app</description><security-constraint><web-resource-collection> <web-resource-name>Success</web-resource-name><url-pattern>/</url-pattern>< Http-method>get |
Test:
http://localhost:8080/DBTest/test.jsp
will be connected through SSL and form authentication. User passwords can be added in User_roles, and users.
5. Garbled Chinese problem:
MySQL default encoding ISO
Tomcat Request transfer encoded ISO
If you want to display Chinese
Add in *.jsp
If it is garbled in data transmission (such as the data read from the MySQL database with the servlet), use the following two transcoding function transcoding, if you do not know which code to convert to which encoding, try more.
transcoding GBK to ISO public string Toiso (String input) { try { byte[] bytes = input.getbytes ("GBK"); return new String (bytes, "iso8859-1"); } catch (Exception ex) { } return input; } transcoding IS0 Turn GBK public string TOGBK (String input) { try { byte[] bytes = input.getbytes ("iso8859-1"); return new String (bytes, "GBK"); } catch (Exception ex) { } return input; }
