spring mvc 与mybatis 的整合.
加入配置文件:

配置数据源监听器:

配置数据源spring-dataSource.xml

配置连接属性
#hibernate.dialect=org.hibernate.dialect.OracleDialect #driverClassName=oracle.jdbc.driver.OracleDriver #validationQuery=SELECT 1 FROM DUAL #jdbc_url=jdbc:oracle:thin:@localhost:1521:orcl #jdbc_username=sypro #jdbc_password=sypro hibernate.dialect=org.hibernate.dialect.MySQLDialect driverClassName=com.mysql.jdbc.Driver validationQuery=SELECT 1 jdbc_url=jdbc:mysql://localhost:3306/c_sai?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull jdbc_username=root jdbc_password= #hibernate.dialect=org.hibernate.dialect.SQLServerDialect #driverClassName=net.sourceforge.jtds.jdbc.Driver #validationQuery=SELECT 1 #jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/sy #jdbc_username=sa #jdbc_password=123456 #hibernate.dialect=org.hibernate.dialect.DerbyDialect #driverClassName=org.apache.derby.jdbc.EmbeddedDriver #validationQuery=SELECT 1 #jdbc_url=jdbc:derby:sy;create=true #jdbc_username=sypro #jdbc_password=sypro #jndiName=java:comp/env/dataSourceName hibernate.hbm2ddl.auto=update hibernate.show_sql=true hibernate.format_sql=true sessionInfoName=sessionInfo uploadFieldName=filedata uploadFileMaxSize=20971520 uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,mid uploadDirectory=attached
修改serviceImpl
package com.sd.test.service.impl; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.sd.test.dao.TTestMapper; import com.sd.test.model.TTest; import com.sd.test.service.TestService; @Service public class TestServiceImpl implements TestService { @Resource private TTestMapper mapper; @Override public void save(Object obj) { int i = this.mapper.insert((TTest) obj); System.out.println("save = " + i); System.out.println("save"); } @Override public Object selectOne(Object obj) { System.out.println("selectOne"); TTest tt = null; tt = this.mapper.selectByPrimaryKey(Integer.parseInt(obj.toString())); return tt; } @Override public Object put(Object obj) { System.out.println("put"); return this.mapper.insert((TTest) obj); } }
controller 代码如下:
package com.sd.test.controller; import java.io.IOException; import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.sd.test.model.TTest; import com.sd.test.service.TestService; @Controller @RequestMapping("/test") public class TestController { @Resource private TestService testService; @RequestMapping("selectOne") public void findById(HttpServletRequest request, HttpServletResponse response) throws IOException { String id = request.getParameter("id"); Object obj = this.testService.selectOne(Integer.parseInt(id)); response.getWriter().print(obj); } @RequestMapping("save") public void save(HttpServletRequest request, HttpServletResponse response) { String name = request.getParameter("name"); TTest t = new TTest(); t.setUsername(name); this.testService.save(t); } @RequestMapping("tsave") public void tsave(HttpServletRequest request, HttpServletResponse response) { String name = request.getParameter("name"); TTest t = new TTest(); t.setUsername(name); int i = (Integer) this.testService.put(t); System.out.println(i); }
启动测试.
http://localhost:8080/prot/test/selectOne.do?id=1
页面上输出:
com.sd.test.model.TTest@9db6ecb
http://localhost:8080/prot/test/save.do?name=userNo1
控制台输出:
save = 1
save
