在做Java Web项目的时候，不可避免的就要使用到数据库，下面就是在IDEA中添加mysql依赖的方法。 如果你看到这里，就表示你弄懂了IDEA，maven和Tomcat等，所以... 只需要在pom.xml中添加依赖就可以了，下面是我的配置文件。
4.0.0 com.suixue example 1.0-SNAPSHOT
junit junit 4.11 jar test
org.springframework spring-context 4.1.6.RELEASE jar log4j log4j 1.2.17 jar
com.fasterxml.jackson.core jackson-core 2.2.1
com.fasterxml.jackson.core jackson-databind 2.1.3
com.fasterxml.jackson.core jackson-annotations 2.1.2 mysql mysql-connector-java 5.1.25 红色区域就是添加mysql依赖的代码哦，若版本不一样，可以再version中进行更改。 添加依赖后，IDEA就会自动为我们下载需要的jar包了哦！
各数据库连接配置与maven依赖安装
各种数据库Hibernate链接配置
Derby
db driver maven dependency
< dependency > < groupId >org.apache.derby</ groupId > < artifactId >derbyclient</ artifactId > < version >10.2.2.0</ version > </ dependency > |
hibernate.properties
hibernate.dialect=org.hibernate.dialect.DerbyDialect hibernate.connection.driver_class=org.apache.derby.jdbc.ClientDriver hibernate.connection.url=jdbc:derby: //localhost/trails;create=true hibernate.connection.username=any hibernate.connection.password=value hibernate.hbm2ddl.auto=update |
MySQL
 | MySQL throws an EOFException when the database connection has been closed after the lease has expired, but it works again on subsequent requests. There is a reported issue with DBCP and the MySQL driver. Check the JIRA issue for more info and a possible solution |

手动安装Maven依赖包
例如要安装这样一个依赖到maven本地仓库：
1.将此依赖添加到项目的pom.xml
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>3.0</version>
</dependency>
2.在命令行中执行install命令
mvn install:install-file -Dfile=sqljdbc4-3.0.jar -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc4 -Dversion=3.0 -Dpackaging=jar
3.将sqljdbc4-3.0.jar拷贝到此依赖安装目录
将sqljdbc4-3.0.jar拷贝到X:\Documents and Settings\%USER%\.m2\repository\com\microsoft\sqlserver\sqljdbc4\3.0 中即可.
