Spring和MyBatis整合

在common工程加入Spring和MyBatis整合需要的依赖

在ui-manger项目中加入

jdbc.properties

jdbc.user=root

jdbc.password=root

jdbc.url=jdbc:mysql://localhost:3306/atcrowdfunding?rewriteBatchedStatements=true&useUnicode=true&characterEncoding=utf8

jdbc.driver=com.mysql.jdbc.Driver

jdbc.maxActive=50

jdbc.maxWait=10000

jdbc.timeBetweenEvictionRunsMillis=60000

jdbc.minEvictableIdleTimeMillis=300000

jdbc.testWhileIdle=true

log4j.properties

For JBoss: Avoid to setup Log4J outside $JBOSS_HOME/server/default/deploy/log4j.xml!

For all other servers: Comment out the Log4J listener in web.xml to activate Log4J.

DEBUG < INFO < WARN < ERROR < FATAL

log4j.rootLogger=DEBUG, a, logfile

log4j.appender.a=org.apache.log4j.ConsoleAppender

log4j.appender.a.layout=org.apache.log4j.PatternLayout

log4j.appender.a.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,S} %-5p [%c] %l - %m%n

log4j.appender.logfile=org.apache.log4j.RollingFileAppender

log4j.appender.logfile.File=D:/atcrowdfunding.log

log4j.appender.logfile.MaxFileSize=512KB

Keep three backup files.

log4j.appender.logfile.MaxBackupIndex=3

Pattern to output: date priority [category] - message

测试类

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations=“classpath:spring-tx.xml”)

public class AtCrowdfundingTest {

@Autowired

private DataSource dataSource;

@Test

public void testDataSource() throws SQLException {

Connection connection = dataSource.getConnection();

System.out.println(connection);

}

}

将spring-tx.xml,jdbc.properties文件放到测试src/test/resources下

如果出现下列错误

发现报错add添加junit.jar和spring-test

或者在ui-manger项目的pom.xml文件中

4.0.0

com

parent

0.0.1-SNAPSHOT

ui-manager

war

junit

junit

com

component

0.0.1-SNAPSHOT

org.springframework

spring-test

如果还有报错

在common项目的pom.xml中添加

org.springframework

spring-webmvc

Spring和SpringMVC整合

创建SpringMVC的配置文件

spring-mvc.xml

在common工程中加入Web开发相关依赖，之前如果添加过就不用再添加了

org.springframework

spring-webmvc

jstl

jstl

在ui-manger工程加入Web开发相关依赖

javax.servlet

servlet-api

provided

javax.servlet.jsp

jsp-api

provided

在spring-mvc.xml中加入名称空间

配置spring-mvc.xml

mvc:annotation-driven/

mvc:default-servlet-handler/

在web.xml中配置

web.xml

ui-manager

contextConfigLocation
