resteasy + mybatis 项目搭建
1.新建maven项目
pom.xml
4.0.0
com.baosight.webapp
Invoice
war
0.0.1-SNAPSHOT
Invoice Maven Webapp
http://maven.apache.org
junit
junit
3.8.1
test
org.jboss.resteasy
resteasy-jaxrs
3.0.14.Final
org.jboss.resteasy
resteasy-jackson-provider
3.0.14.Final
org.jboss.resteasy
resteasy-multipart-provider
3.0.14.Final
com.github.growth2
lazybones-mybatis-generator-plugin
0.0.1
UTF-8
Invoice
2.引入其他jar包
前两个jar包设置cors跨域
后两个jar包设置数据库连接
3.web.xml的配置
Archetype Created Web Application
resteasy-servlet
org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
javax.ws.rs.Application
com.baosight.webapp.app.InvoiceApplication
resteasy-servlet
/services/*
CORS
com.thetransactioncompany.cors.CORSFilter
CORS
/*
CORS
/*
/services/*
之前写成/*造成webapp下的页面无法请求
后面配置的是cors跨域
4.mybatis的配置
1）jdbc连接：jdbc.properties
jdbc.url=jdbc\:oracle\:thin\:@127.0.0.1\:1521\:xe
jdbc.username=briup
jdbc.password=briup
jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
