從.Net到Java學習第十一篇——SpringBoot登入實現
阿新 • • 發佈：2019-01-16
通過前面10篇文章的學習，相信我們對SpringBoot已經有了一些瞭解，那麼如何來驗證我們的學習成果呢？當然是通過做專案來證明啦！所以從這一篇開始我將會對之前自己做的.net專案用java來重寫。這一篇，我們來現實登入模組。
一提到登入，我們首先想到的基本的功能點就有如下：
輸入：使用者名稱、密碼、驗證碼。
登入成功後，跳轉到後臺。如果未登入直接訪問後臺，將會跳轉到登入頁面。
這裡暫不考慮複雜的登入實現。
技術選型，沿用前面用到的知識點。那麼這裡較之於之前的文章，新用到的一個就是圖片驗證碼，一個就是許可權攔截器了。
1、新建spring boot web專案，具體配置資訊如pom.xml所示：
<?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> <View CodegroupId>com.yujie</groupId> <artifactId>website</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>website</name> <description>通用角色許可權管理系統</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.13.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-web</artifactId> </dependency> <!--mybatis--> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.2</version> </dependency> <!--mysql--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <!--整合druid，使用連線池--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.0</version> </dependency> <!--thymeleaf--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>net.sourceforge.nekohtml</groupId> <artifactId>nekohtml</artifactId> <version>1.9.22</version> </dependency> <!-- 分頁外掛 --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> <version>1.1.2</version> </dependency> <!--單元測試--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!--熱部署--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <!-- mybatis generator 自動生成程式碼外掛 --> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <configuration> <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile> <overwrite>true</overwrite> <verbose>true</verbose> </configuration> </plugin> </plugins> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> <filtering>true</filtering> </resource> </resources> </build> </project>
2、準備資料庫、資料表。這裡只用一張使用者表t_user.sql

3、對專案進行配置。我對配置項進行了詳實的註釋，如有不懂的，自己翻閱相關文件。
application.yml
spring:
