使用springboot暴露oracle数据接口的问题

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：

 <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc6</artifactId>
            <version>11.2.0.1.0</version>
        </dependency>

3.编辑application.yml

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：

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

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

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:

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：

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。
