快速搭建springboot项目

下载springboot的包

链接: https://spring.io/projects/spring-boot

在这里插入图片描述

使用idea或者eclipse导入Maven项目

在pom.xml中添加依赖

		<!--mybatis的依赖包-->
		<dependency>
			<groupId>org.mybatis.spring.boot</groupId>
			<artifactId>mybatis-spring-boot-starter</artifactId>
			<version>1.3.0</version>
		</dependency>
		<!--oracle的依赖包-->
		<dependency>
			<groupId>com.oracle</groupId>
			<artifactId>ojdbc6</artifactId>
			<version>11.2.0</version>
		</dependency>
		<!--springboot 热部署-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-devtools</artifactId>
			<optional>true</optional>
		</dependency>

<!--插件-->
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <fork>true</fork>
            </configuration>
        </plugin>
    </plugins>
</build>

##dataSource数据源配置
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@127.0.0.1:1521/orcl
spring.datasource.username=yjy
spring.datasource.password=yjy


##Mybatis映射实体类和映射文件配置,扫描哪个包
mybatis.typeAliasesPackage=com.cgzx.certificates.entity
mybatis.mapperLocations=classpath:com/cgzx/certificates/dao/*Mapper.xml

#debug
logging.level.org.springframework=WARN
logging.level.com.github.ArchiveService.dao=DEBUG
loggin.file=logs/srping-boot-loggin.log

#service端口配置和项目路径配置
server.port=8082
#server.servlet.context-path=/certificates

项目目录如下

资源放在resources中,比如html,jar包

三个层的代码

controller层

package com.cgzx.certificates.controller;

import com.cgzx.certificates.entity.User;
import com.cgzx.certificates.service.UserService;
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
@RequestMapping(value = "/select")
public class controller {
    @Autowired
    private UserService userService;
    @RequestMapping(value = "/getUser")
    public List<User> getUser(){
        System.out.println("jinlaile");
        List<User> user = userService.getUser();
        System.out.println(user);
        return user;
    }
    @RequestMapping(value = "/ok")
    public String ok(){
        System.out.println("ok");
    return "ok";
    }
}

Service层

package com.cgzx.certificates.service;

import com.cgzx.certificates.dao.UserMapper;
import com.cgzx.certificates.entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
@Service
public class UserServiceImpl implements UserService{
    @Autowired
    private UserMapper userMapper;
    @Override
    public List<User> getUser() {
        List<User> user = userMapper.getUser();
        return user;
    }
}

dao层

package com.cgzx.certificates.dao;

import com.cgzx.certificates.entity.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
@Mapper
public interface UserMapper {
    List<User> getUser();
}

运行结果

访问资源
访问select/getUser接口成功拿到数据
