Sprigmvc項目轉為springboot的方法

是否有老掉牙的springmvc項目，想轉成springboot項目，看這個文章就對了。

說明

如果你的項目連maven項目都不是，請自行轉為maven項目，在按照本教程進行。

本教程適用於spring+springmvc+mybatis+shiro的maven項目。

1.修改pom文件依賴

刪除之前的spring依賴，添加springboot依賴

<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version></parent><dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!-- 這個是剔除掉自帶的tomcat部署的--> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <!-- tomcat容器部署--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <!--<scope>compile</scope>--> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.0</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency> <!-- 支持@ConfigurationProperties 註解--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> </dependency></dependencies>

添加springboot構建插件

<plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>1.5.9.RELEASE</version> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin></plugins>

2.添加application啟動文件

注意，如果Application在controller，service，dao的上一層包裡，無需配置@ComponentScan ,

否則，需要指明要掃描的包。

 @SpringBootApplication//@ComponentScan({"com.cms.controller","com.cms.service","com.cms.dao"})public class Applicationextends SpringBootServletInitializer{ @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application){ return application.sources(Application.class); } public static void main(String[] args)throws Exception { SpringApplication.run(Application.class, args); }}

3.添加springboot配置文件

在resources下面添加application.properties文件

添加基本​​配置#默認前綴server.contextPath=/# 指定環境spring.profiles.active=local# jsp配置spring.mvc.view.prefix=/WEB-INF/jsp/spring.mvc.view.suffix=.jsp#log配置文件logging.config=classpath:logback-cms.xml#log路徑logging.path=/Users/mac/work-tommy/cms-springboot/logs/#數據源spring.datasource.name=adminDataSourcespring.datasource.driverClassName = com.mysql.jdbc.Driverspring.datasource.url = jdbc:mysql://localhost:3306/mycms?useUnicode=true&autoReconnect=true&characterEncoding=utf-8spring.datasource.username = rootspring.datasource.password = 123456

4.使用@Configuration注入配置

注入mybatis配置,分頁插件請自主選擇

@Configuration@MapperScan(basePackages = "com.kuwo.dao",sqlSessionTemplateRef = "adminSqlSessionTemplate")public class AdminDataSourceConfig{ @Bean(name = "adminDataSource") @ConfigurationProperties(prefix = "spring.datasource") @Primary public DataSource adminDataSource(){ return DataSourceBuilder.create().build(); } @Bean(name = "adminSqlSessionFactory") @Primary public SqlSessionFactory adminSqlSessionFactory(@Qualifier("adminDataSource")DataSource dataSource)throws Exception { SqlSessionFactoryBean bean = new SqlSessionFactoryBean(); bean.setDataSource(dataSource); //分頁插件// PageHelper pageHelper = new PageHelper(); PagePlugin pagePlugin = new PagePlugin();// Properties props = new Properties();// props.setProperty("reasonable", "true");// props.setProperty("supportMethodsArguments", "true");// props.setProperty("returnPageInfo", "check");// props.setProperty("params", "count=countSql");// pageHelper.setProperties(props); //添加插件bean.setPlugins(new Interceptor[]{pagePlugin}); // 添加mybatis配置文件bean.setConfigLocation(new DefaultResourceLoader().getResource("classpath:mybatis/mybatis-config.xml")); // 添加mybatis映射文件bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mybatis/system/*.xml")); return bean.getObject(); } @Bean(name = "adminTransactionManager") @Primary public DataSourceTransactionManager adminTransactionManager(@Qualifier("adminDataSource")DataSource dataSource){ return new DataSourceTransactionManager(dataSource); } @Bean(name = "adminSqlSessionTemplate") @Primary public SqlSessionTemplate adminSqlSessionTemplate(@Qualifier("adminSqlSessionFactory")SqlSessionFactory sqlSessionFactory)throws Exception { return new SqlSessionTemplate(sqlSessionFactory); }}

添加Interceptor配置,注意addInterceptor的順序，不要搞亂了

@Configurationpublic class InterceptorConfigurationextends WebMvcConfigurerAdapter{ @Override public void addInterceptors(InterceptorRegistry registry){ registry.addInterceptor(new LoginHandlerInterceptor()); }}

添加shiro配置文件

注意：本來使用redis做session緩存，但是和shiro集成發現一個問題，user對象存儲以後，從shiro中獲取後，無法進行類型轉換，所以暫時放棄了redis做session緩存。

 @Configurationpublic class ShiroConfiguration{ @Value("${spring.redis.host}") private String host; @Value("${spring.redis.port}") private int port; @Value("${spring.redis.timeout}") private int timeout; @Bean public static LifecycleBeanPostProcessor getLifecycleBeanPostProcessor(){ return new LifecycleBeanPostProcessor(); } /** * ShiroFilterFactoryBean 處理攔截資源文件問題。 * 注意：單獨一個ShiroFilterFactoryBean配置是或報錯的，因為在* 初始化ShiroFilterFactoryBean的時候需要注入：SecurityManager * Filter Chain定義說明1、一個URL可以配置多個Filter，使用逗號分隔2、當設置多個過濾器時，全部驗證通過，才視為通過3、部分過濾器可指定參數，如perms，roles * */ @Bean public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager){ System.out.println("ShiroConfiguration.shirFilter()"); ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean(); // 必須設置SecurityManager shiroFilterFactoryBean.setSecurityManager(securityManager); // 如果不設置默認會自動尋找Web工程根目錄下的"/login.jsp"頁面shiroFilterFactoryBean.setLoginUrl("/login_toLogin"); // 登錄成功後要跳轉的鏈接shiroFilterFactoryBean.setSuccessUrl("/usersPage"); //未授權界面; shiroFilterFactoryBean.setUnauthorizedUrl("/403"); //攔截器. Map<String,String> filterChainDefinitionMap = new LinkedHashMap<>(); //配置退出過濾器,其中的具體的退出代碼Shiro已經替我們實現了filterChainDefinitionMap.put("/logout", "logout"); filterChainDefinitionMap.put("/login_toLogin", "anon"); filterChainDefinitionMap.put("/login_login", "anon"); filterChainDefinitionMap.put("/static/login/**","anon"); filterChainDefinitionMap.put("/static/js/**","anon"); filterChainDefinitionMap.put("/uploadFiles/uploadImgs/**","anon"); filterChainDefinitionMap.put("/code.do","anon"); filterChainDefinitionMap.put("/font-awesome/**","anon"); //<!-- 過濾鏈定義，從上向下順序執行，一般將/*​​放在最為下邊-->:這是一個坑呢，一不小心代碼就不好使了; //<!-- authc:所有url都必須認證通過才可以訪問; anon:所有url都都可以匿名訪問--> filterChainDefinitionMap.put("/**", "authc"); shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap); return shiroFilterFactoryBean; } @Bean public SecurityManager securityManager(){ DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); //設置realm. securityManager.setRealm(myShiroRealm()); // 自定義緩存實現使用redis //securityManager.setCacheManager(cacheManager()); // 自定義session管理使用redis securityManager.setSessionManager(sessionManager()); return securityManager; } @Bean public ShiroRealm myShiroRealm(){ ShiroRealm myShiroRealm = new ShiroRealm();// myShiroRealm.setCredentialsMatcher(hashedCredentialsMatcher()); return myShiroRealm; }} /** * 開啟shiro aop註解支持. * 使用代理方式;所以需要開啟代碼支持; * @param securityManager * @return */ @Bean public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager){ AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor(); authorizationAttributeSourceAdvisor.setSecurityManager(securityManager); return authorizationAttributeSourceAdvisor; } /** * 配置shiro redisManager * 使用的是shiro-redis開源插件* @return */ public RedisManager redisManager(){ RedisManager redisManager = new RedisManager(); redisManager.setHost(host); redisManager.setPort(port); redisManager.setExpire(1800); redisManager.setTimeout(timeout); // redisManager.setPassword(password); return redisManager; } /** * cacheManager 緩存redis實現* 使用的是shiro-redis開源插件* @return */ public RedisCacheManager cacheManager(){ RedisCacheManager redisCacheManager = new RedisCacheManager(); redisCacheManager.setRedisManager(redisManager()); return redisCacheManager; } /** * RedisSessionDAO shiro sessionDao層的實現通過redis * 使用的是shiro-redis開源插件*/ @Bean public RedisSessionDAO redisSessionDAO(){ RedisSessionDAO redisSessionDAO = new RedisSessionDAO(); redisSessionDAO.setRedisManager(redisManager()); return redisSessionDAO; } @Bean public DefaultWebSessionManager sessionManager(){ DefaultWebSessionManager sessionManager = new DefaultWebSessionManager();// sessionManager.setSessionDAO(redisSessionDAO()); return sessionManager; }}
