本文主要給大家介紹CAS4.0連接mysql數據庫的詳細步驟，文章內容都是筆者用心摘選和編輯的，具有一定的針對性，對大家的參考意義還是比較大的，下面跟筆者一起了解下CAS4.0連接mysql數據庫的詳細步驟吧。
步驟如下
一：
在cas-4.0.0\cas-server-webapp\pom.xml中添加依賴后（如下方所示），打開cmd在cas-4.0.0\cas-server-webapp文件夾下運行mvn clean package，然后將cas-4.0.0\cas-server-webapp\target下的cas.war包部署至tomcat
Xml代碼
<dependency>
<groupId>org.jasig.cas</groupId>
<artifactId>cas-server-support-jdbc</artifactId>
<version>${project.version}</version>
<type>jar</type>
</dependency>
<!-- https://mvnrepository.com/artifact/commons-dbcp/commons-dbcp -->
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
<version>1.4</version>
</dependency>
<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.6</version>
</dependency>
二：
本地創建數據庫，并新建表 cas_user，創建語句如下載
Sql代碼
create table cas_user (
id bigint not null auto_increment,
email varchar(255),
username varchar(255) not null unique,
name varchar(255),
password varchar(255),
primary key (id)
) ENGINE=InnoDB;
三：
配置數據庫相關文件，在tomcat-for-cas\webapps\cas\WEB-INF\deployerConfigContext.xml中配置對應的datasource，數據庫地址，用戶名，密碼，以及查詢用戶的sql。需要注意的是，如果是自己建的表，要把相應的字段名，數據庫名替換掉，以及，不要忘記注釋掉默認用戶名密碼的配置（casuser/Mellon）。下載以下配置可以全拷貝
