新建一个Spring Initializr项目
2.把pom.xml文件中的oracle依赖换成自己的oracle版本依赖：
原来的：
现在的：
|
1 2 3 4 5 |
<dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version> 11.2 . 0.1 . 0 </version> </dependency> |
3.编辑application.yml
|
1 2 3 4 5 6 |
spring: datasource: driver- class -name: oracle.jdbc.driver.OracleDriver url: jdbc:oracle:thin: @192 .168. 21.200 : 1521 :orcl username: alisa password: alisa |
4.创建实例类——Userinfos.java：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 |
package cn.alisa.myspboracle.entity;
import java.util.Date;
public class Userinfos { private int userid; private String username; private Date birthyear; private float userhight;
public int getUserid() { return userid; }
public void setUserid( int userid) { this .userid = userid; }
public String getUsername() { return username; }
public void setUsername(String username) { this .username = username; }
public Date getBirthyear() { return birthyear; }
public void setBirthyear(Date birthyear) { this .birthyear = birthyear; }
public float getUserhight() { return userhight; }
public void setUserhight( float userhight) { this .userhight = userhight; } } |
创建接口类——UserinfosDAO.java
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
package cn.alisa.myspboracle.dao;
import cn.alisa.myspboracle.entity.Userinfos; import org.apache.ibatis.annotations.Select;
import java.util.List;
public interface UserinfosDAO { @Select ( "select userid,username,birthyear,userhight from userinfos" ) public List<Userinfos>findAll();
@Select ( "select userid,username,birthyear,userhight from userinfos where username like '%${name}%'" ) public List<Userinfos>findUserSameName(String name); } |
创建服务类——UserinfosService.java
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
package cn.alisa.myspboracle.service;
import cn.alisa.myspboracle.dao.UserinfosDAO; import cn.alisa.myspboracle.entity.Userinfos; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;
import java.util.List;
@Service public class UserinfosService { @Autowired private UserinfosDAO udao;
public List<Userinfos>searchAll(){ return udao.findAll(); }
public List<Userinfos>sameName(String name){ return udao.findUserSameName(name); } } |
创建控制层类——InitCtrl.java:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
package cn.alisa.myspboracle.ctrl;
import cn.alisa.myspboracle.entity.Userinfos; import cn.alisa.myspboracle.service.UserinfosService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;
import java.util.List;
@RestController public class InitCtrl { @Autowired private UserinfosService userinfosService;
@RequestMapping ( "/all" ) public List<Userinfos>init(){ return userinfosService.searchAll(); }
@RequestMapping ( "/same" ) public List<Userinfos>same(String name){ return userinfosService.sameName(name); } } |
编辑MyspboracleApplication.java类：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
package cn.alisa.myspboracle;
import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication @MapperScan ( "cn.alisa.myspboracle.dao" ) public class MyspboracleApplication {
public static void main(String[] args) {
SpringApplication.run(MyspboracleApplication. class , args); }
} |
运行此类（MyspboracleApplication.java），在浏览器中输入"http://localhost:8080/all"或者"http://localhost:8080/same?name=l"即可看到想要的结果。
