篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SpringBoot-06：SpringBoot增删改查一套完整的考试案例相关的知识，希望对你有一定的参考价值。
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥-------------
本此博客记录一套考试题，随后我把项目以及题目发到github上，简单的说一下springboot的开发
本此考试题用Spring+SpringMVC+MyBatis+SpringBoot+mysql+Druid+.yml配置文件+thymeleaf模板引擎
我会把大量源码放上来，以及整合需要的注意点，大家可以一会去github上下载观看
项目概览：
一，jar包，pom.xml中的配置
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>z05springbootmyself_exam</artifactId> <packaging>war</packaging> <name>z05springbootmyself_exam Maven Webapp</name> <!-- FIXME change it to the project\'s website --> <url>http://www.example.com</url> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.3.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </dependency> <!-- 核心依赖 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- 可以实现热部署，在IDEA上实现热部署还需一些额外的配置，请查阅资料 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> <scope>runtime</scope> </dependency> <!-- JDBC for mysql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- mybatis --> <!--mybatis--> <!-- https://mvnrepository.com/artifact/org.mybatis.spring.boot/mybatis-spring-boot-starter --> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.1</version> </dependency> <!--fastJson--> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.12</version> </dependency> <!--druid--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.18</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.1</version> </dependency> <!--thymeleaf 新的模板引擎，比jsp要出色--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!--jdbc--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <!-- 分页插件 --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> <version>1.2.3</version> </dependency> </dependencies> <build> <finalName>z05springbootmyself_exam</finalName> <!--maven插件--> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> <!--xml配置，此是为了将来整合Hibernate或者mybatis 默认没有需要配置 --> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> </resource> </resources> </build> </project>
注意点：如果自己工程不是通过官网骨架创建，自己粘的话，小心粘了俩个parent节点，他不会报错，但是在后续就不会下载jar包了
二，数据库脚本，我给一份
DROP TABLE IF EXISTS `air_quality_index`; CREATE TABLE `air_quality_index` ( `id` int(11) NOT NULL AUTO_INCREMENT, `district` varchar(255) NOT NULL, `monitorTime` datetime NOT NULL ON UPDATE CURRENT_TIMESTAMP, `pm10` int(255) NOT NULL, `pm25` int(255) NOT NULL, `monitoringStation` varchar(255) NOT NULL, `createDate` datetime NOT NULL ON UPDATE CURRENT_TIMESTAMP, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of air_quality_index -- ---------------------------- INSERT INTO `air_quality_index` VALUES (\'1\', \'西城区\', \'2018-05-22 09:34:05\', \'243\', \'176\', \'灵境胡同监测站\', \'2018-05-22 10:57:21\'); INSERT INTO `air_quality_index` VALUES (\'2\', \'东城区\', \'2018-05-22 09:34:05\', \'27\', \'33\', \'东四监测站\', \'2018-05-22 09:34:35\'); INSERT INTO `air_quality_index` VALUES (\'3\', \'海淀区\', \'2018-05-22 09:34:05\', \'21\', \'30\', \'航天桥监测站\', \'2018-05-22 09:34:35\'); INSERT INTO `air_quality_index` VALUES (\'4\', \'丰台区\', \'2018-05-22 09:34:05\', \'24333\', \'17\', \'七里庄监测站\', \'2018-05-22 10:55:20\'); INSERT INTO `air_quality_index` VALUES (\'5\', \'西城区\', \'2018-05-22 09:58:03\', \'100\', \'1\', \'北京某地\', \'2018-06-22 16:41:51\'); INSERT INTO `air_quality_index` VALUES (\'6\', \'东城区\', \'2018-05-22 09:58:03\', \'22\', \'22\', \'山东某地222333\', \'2018-05-22 10:54:36\'); INSERT INTO `air_quality_index` VALUES (\'7\', \'西城区\', \'2018-05-22 09:58:03\', \'22\', \'22\', \'天津某地\', \'2018-05-22 10:57:41\'); INSERT INTO `air_quality_index` VALUES (\'8\', \'西城区\', \'2018-05-22 09:58:03\', \'122\', \'232\', \'山东222\', \'2018-05-22 10:58:59\'); INSERT INTO `air_quality_index` VALUES (\'9\', \'0\', \'2018-05-22 09:58:03\', \'22\', \'22\', \'北京某地\', \'2018-05-22 11:26:42\'); INSERT INTO `air_quality_index` VALUES (\'10\', \'西城区\', \'2018-05-22 09:58:03\', \'22\', \'22\', \'天津某地\', \'2018-06-22 16:42:17\'); INSERT INTO `air_quality_index` VALUES (\'11\', \'西城区\', \'2018-05-22 09:58:03\', \'1\', \'22\', \'灵境胡同监测站\', \'2018-06-22 16:42:50\');
三，application.yml的配置
server: #端口号 port: 8080 spring: #模板引擎 thymeleaf: prefix: classpath:/templates/ mode: html5 cache: false #阿里的druid datasource: name: test url: jdbc:mysql:///exam_air username: root password: type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select \'x\' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20 mybatis: #映射的xml文件 mapper-locations: classpath:mapping/*.xml #别名 type-aliases-package: com.happy.entity
注意点：他是一种新的模板，yml不可以使用制表符TAB，它通过空格表示层级关系，同样的节点反复出现会有问题
我在里面配置了tomcat的端口，druid的数据源，以及mybatis的部分配置
四，项目骨架预览
五，thymeleaf模板的创建，他是以.html后缀名结尾的文件
1.主页面：
