0x1 環境java
1. 系統:Windows 10 mysql
2. IDE:IntelliJ IDEA 2018.3 x64git
0x2 建立項目github
1.建立一個SpringBoot項目web
選擇Spring Initailizr >Nextspring
簡單配置便可>Nextsql
選擇項目所需依賴>Next數據庫
選擇項目工做空間[隨便寫]:目錄不存在會自動建立 > Next springboot
建立好後,idea就會加載依賴包,並彈出提示,Meven項目須要導入依賴,選擇自動導包mybatis
等待一會....當右下角沒有進度條就說明好了
2. 建立項目結構
這三個文件能夠刪除
依次建立目錄:controller層,domain層(entity),mapper層,query層,service層,建立好就是這樣子......
注意:本文不使用application.properties文件 而使用更加簡潔的application.yml文件,可能大家已經注意到了項目中有四個 yml文件這是爲何?
由於如今一個項目有好多環境,開發環境,測試環境,準生產環境,生產環境,每一個環境的參數不一樣,因此咱們就能夠把每一個環境的參數配置到 yml文件中
在Spring Boot中多環境配置文件名須要知足application-{profile}.yml的格式,其中{profile}對應你的環境標識,好比:
application.yml:主文件
application-dev.yml:開發環境
application-test.yml:測試環境
application-prod.yml:生產環境
須要加載那個文件就在在 application.yml 文件中經過spring.profiles.active屬性來設置,其值對應{profile}值。好比
建立數據庫表
CREATE TABLE `user` ( `id` BIGINT(32) NOT NULL AUTO_INCREMENT, `userName` varchar(32) NOT NULL, `passWord` varchar(50) NOT NULL, `realName` varchar(32) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
3. 完善結構
①User.java
1 package xyz.bit1024.sunny.domain; 2 3 /** 4 * @ClassName User 5 * @Date 2019-06-15 16:14 6 * @Author xiaozhi 7 * @Version 1.0.0 8 * @Since JDK 1.8 9 * @Description 實體類 10 */ 11 public class User { 12 private Long id; 13 private String userName; 14 private String passWord; 15 private String realName; 16 17 public Long getId() { 18 return id; 19 } 20 21 public void setId(Long id) { 22 this.id = id; 23 } 24 25 public String getUserName() { 26 return userName; 27 } 28 29 public void setUserName(String userName) { 30 this.userName = userName; 31 } 32 33 public String getPassWord() { 34 return passWord; 35 } 36 37 public void setPassWord(String passWord) { 38 this.passWord = passWord; 39 } 40 41 public String getRealName() { 42 return realName; 43 } 44 45 public void setRealName(String realName) { 46 this.realName = realName; 47 } 48 49 @Override 50 public String toString() { 51 return "User{" + 52 "id=" + id + 53 ", userName='" + userName + '\'' + 54 ", passWord='" + passWord + '\'' + 55 ", realName='" + realName + '\'' + 56 '}'; 57 } 58 }
筆者按:在實體類中覆寫toString方法有助於查錯---<阿里巴巴Java開發手冊>
UserMapper.java
1 package xyz.bit1024.sunny.mapper; 2 3 import xyz.bit1024.sunny.domain.User; 4 5 import java.util.List; 6 7 /** 8 * @ClassName UserMapper 9 * @Date 2019-06-15 16:21 10 * @Author xiaozhi 11 * @Version 1.0.0 12 * @Since JDK 1.8 13 * @Description 14 */ 15 public interface UserMapper { 16 List<User> listAll(); 17 }
UserQuery.java 查詢對象
1 package xyz.bit1024.sunny.query; 2 3 /** 4 * @ClassName UserQuery 5 * @Date 2019-06-15 16:28 6 * @Author xiaozhi 7 * @Version 1.0.0 8 * @Since JDK 1.8 9 * @Description 10 */ 11 public class UserQuery { 12 }
IUserService.java:接口層,面向接口思想
1 package xyz.bit1024.sunny.service; 2 3 import xyz.bit1024.sunny.domain.User; 4 5 import java.util.List; 6 7 /** 8 * @ClassName IUserService 9 * @Date 2019-06-15 16:17 10 * @Author xiaozhi 11 * @Version 1.0.0 12 * @Since JDK 1.8 13 * @Description 14 */ 15 public interface IUserService { 16 17 /** 18 * 所有用戶 19 * @return List<User> 20 */ 21 List<User> listAll(); 22 }
在service 層下建立 impl 目錄,並在impl目錄下面建立 IUserService 實現類並實現覆寫父類方法
UserServiceImpl.java
1 package xyz.bit1024.sunny.service.impl; 2 3 import org.springframework.beans.factory.annotation.Autowired; 4 import org.springframework.stereotype.Service; 5 import xyz.bit1024.sunny.domain.User; 6 import xyz.bit1024.sunny.mapper.UserMapper; 7 import xyz.bit1024.sunny.service.IUserService; 8 9 import java.util.List; 10 11 /** 12 * @ClassName UserServiceImpl 13 * @Date 2019-06-15 16:19 14 * @Author xiaozhi 15 * @Version 1.0.0 16 * @Since JDK 1.8 17 * @Description 實現類[業務類] 18 */ 19 @Service 20 public class UserServiceImpl implements IUserService { 21 22 @Autowired 23 private UserMapper userMapper; 24 25 @Override 26 public List<User> listAll() { 27 return userMapper.listAll(); 28 } 29 }
⑥ 在resources 建立mapper目錄,並建立 UserMapper.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> 3 <mapper namespace="xyz.bit1024.sunny.mapper.UserMapper"> 4 <resultMap id="BaseResultMap" type="xyz.bit1024.sunny.domain.User"> 5 <result column="id" jdbcType="BIGINT" property="id" /> 6 <result column="userName" jdbcType="VARCHAR" property="userName" /> 7 <result column="passWord" jdbcType="VARCHAR" property="passWord" /> 8 <result column="realName" jdbcType="VARCHAR" property="realName" /> 9 </resultMap> 10 11 <sql id="Base_Column_List"> 12 id, userName, passWord, realName 13 </sql> 14 <sql id="Base_Column_List_Value"> 15 #{id,jdbcType=Long}, 16 #{userName,jdbcType=VARCHAR}, 17 #{passWord,jdbcType=VARCHAR}, 18 #{realName,jdbcType=VARCHAR} 19 </sql> 20 <select id="listAll" resultMap="BaseResultMap"> 21 select <include refid="Base_Column_List"/> from t_user 22 </select> 23 </mapper>
UserController.java
1 package xyz.bit1024.sunny.controller; 2 3 import org.springframework.beans.factory.annotation.Autowired; 4 import org.springframework.web.bind.annotation.RequestMapping; 5 import org.springframework.web.bind.annotation.RestController; 6 import xyz.bit1024.sunny.domain.User; 7 import xyz.bit1024.sunny.service.IUserService; 8 9 import java.util.List; 10 11 /** 12 * @ClassName UserController 13 * @Date 2019-06-15 16:16 14 * @Author xiaozhi 15 * @Version 1.0.0 16 * @Since JDK 1.8 17 * @Description 18 */ 19 @RestController 20 @RequestMapping("/user") 21 public class UserController { 22 23 //注入Service對象 24 @Autowired 25 private IUserService iUserService; 26 27 @RequestMapping("/listAll") 28 public List<User> listAll(){ 29 return iUserService.listAll(); 30 } 31 }
4 .完善配置
① 配置Mapper掃描包
application-dev.yml
logback.xml
<?xml version="1.0" encoding="UTF-8"?> <configuration> <property name="LOG_HOME" value="./logs" /> <property name="APP_NAME" value="bit1024" /> <include resource="org/springframework/boot/logging/logback/defaults.xml" /> <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{35} - %msg %n</pattern> <charset>UTF-8</charset> </encoder> </appender> <appender name="infoFile" class="ch.qos.logback.core.rolling.RollingFileAppender"> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>INFO</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${LOG_HOME}/${APP_NAME}.info.%d{yyyy-MM-dd}.%i.log</fileNamePattern> <maxFileSize>10MB</maxFileSize> <maxHistory>30</maxHistory> <totalSizeCap>6GB</totalSizeCap> </rollingPolicy> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> <charset>UTF-8</charset> </encoder> </appender> <appender name="warnFile" class="ch.qos.logback.core.rolling.RollingFileAppender"> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>WARN</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${LOG_HOME}/${APP_NAME}.warn.%d{yyyy-MM-dd}.%i.log</fileNamePattern> <maxFileSize>10MB</maxFileSize> <maxHistory>30</maxHistory> <totalSizeCap>6GB</totalSizeCap> </rollingPolicy> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> <charset>UTF-8</charset> </encoder> </appender> <appender name="errorFile" class="ch.qos.logback.core.rolling.RollingFileAppender"> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${LOG_HOME}/${APP_NAME}.error.%d{yyyy-MM-dd}.%i.log</fileNamePattern> <maxFileSize>10MB</maxFileSize> <maxHistory>30</maxHistory> <totalSizeCap>6GB</totalSizeCap> </rollingPolicy> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> <charset>UTF-8</charset> </encoder> </appender> <!--myibatis日誌配置--> <logger name="xyz.bit1024.sunny.mapper" level="INFO"/> <logger name="xyz.bit1024" level="DEBUG"/> <!-- 日誌輸出級別 --> <root level="INFO"> <appender-ref ref="CONSOLE"></appender-ref> <appender-ref ref="infoFile"></appender-ref> <appender-ref ref="warnFile"></appender-ref> <appender-ref ref="errorFile"></appender-ref> </root> </configuration>
構造測試數據
INSERT INTO `springboot`.`t_user` (`id`, `userName`, `passWord`, `realName`) VALUES ('10000001', 'admin', 'admin', '超級管理員'); INSERT INTO `springboot`.`t_user` (`id`, `userName`, `passWord`, `realName`) VALUES ('10000002', 'user1', '123', '用戶1'); INSERT INTO `springboot`.`t_user` (`id`, `userName`, `passWord`, `realName`) VALUES ('10000003', 'user2', '123', '用戶2');
一切完畢只待測試
使用PostMan測試一波
成功,,完美
採坑:
java.sql.SQLException: The server time zone value '�й���ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
修改配置文件:
url: jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
此次的集成就算完了,,有空把登陸+shiro也集成
