本篇文章主要介绍了Sprigmvc项目转为springboot的方法,小妖觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小妖过来看看吧
是否有老掉牙的springmvc项目,想转成springboot项目,看这个文章就对了。说明如果你的项目连maven项目都不是,请自行转为maven项目,在按照本教程进行。本教程适用于spring+springmvc+mybatis+shiro的maven项目。 1.修改pom文件依赖删除之前的spring依赖,添加springboot依赖 ```xml org.springframework.boot spring-boot-starter-parent 1.5.9.RELEASE org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-tomcat org.springframework.boot spring-boot-starter-tomcat compile--> org.mybatis.spring.boot mybatis-spring-boot-starter 1.3.0 org.springframework.boot spring-boot-devtools true org.springframework.boot spring-boot-configuration-processor true org.apache.tomcat.embed tomcat-embed-jasper ``` 添加springboot构建插件 ```xml org.apache.maven.plugins maven-compiler-plugin 1.7 1.7 org.springframework.boot spring-boot-maven-plugin 1.5.9.RELEASE repackage ``` 2.添加application启动文件注意,如果Application在controller,service,dao的上一层包里,无需配置 @ComponentScan ,否则,需要指明要扫描的包。 ```java @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 ```plain 添加基本配置 #默认前缀 server.contextPath=/ # 指定环境 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路径 logging.path=/Users/mac/work-tommy/cms-springboot/logs/ #数据源 spring.datasource.name=adminDataSource spring.datasource.driverClassName = com.mysql.jdbc.Driver spring.datasource.url = jdbc:mysql://localhost:3306/mycms?useUnicode=true&autoReconnect=true&characterEncoding=utf-8 spring.datasource.username = root spring.datasource.password = 123456 ``` 4.使用@Configuration注入配置注入mybatis配置,分页插件请自主选择 ```java @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); //分页插件 // 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的顺序,不要搞乱了 ```java @Configuration public class InterceptorConfigurationextends WebMvcConfigurerAdapter{ @Override public void addInterceptors(InterceptorRegistry registry){ registry.addInterceptor(new LoginHandlerInterceptor()); } } ``` 添加shiro配置文件注意:本来使用redis做session缓存,但是和shiro集成发现一个问题,user对象存储以后,从shiro中获取后,无法进行类型转换,所以暂时放弃了redis做session缓存。 ```java @Configuration public 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 处理拦截资源文件问题。 * 注意:单独一个ShiroFilterFactoryBean配置是或报错的,因为在 * 初始化ShiroFilterFactoryBean的时候需要注入:SecurityManager * Filter Chain定义说明 1、一个URL可以配置多个Filter,使用逗号分隔 2、当设置多个过滤器时,全部验证通过,才视为通过 3、部分过滤器可指定参数,如perms,roles * */ @Bean public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager){ System.out.println("ShiroConfiguration.shirFilter()"); ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean(); // 必须设置 SecurityManager shiroFilterFactoryBean.setSecurityManager(securityManager); // 如果不设置默认会自动寻找Web工程根目录下的"/login.jsp"页面 shiroFilterFactoryBean.setLoginUrl("/login_toLogin"); // 登录成功后要跳转的链接 shiroFilterFactoryBean.setSuccessUrl("/usersPage"); //未授权界面; shiroFilterFactoryBean.setUnauthorizedUrl("/403"); //拦截器. Map filterChainDefinitionMap = new LinkedHashMap(); //配置退出 过滤器,其中的具体的退出代码Shiro已经替我们实现了 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"); //:这是一个坑呢,一不小心代码就不好使了; // filterChainDefinitionMap.put("/**", "authc"); shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap); return shiroFilterFactoryBean; } @Bean public SecurityManager securityManager(){ DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); //设置realm. securityManager.setRealm(myShiroRealm()); // 自定义缓存实现 使用redis //securityManager.setCacheManager(cacheManager()); // 自定义session管理 使用redis securityManager.setSessionManager(sessionManager()); return securityManager; } @Bean public ShiroRealm myShiroRealm(){ ShiroRealm myShiroRealm = new ShiroRealm(); // myShiroRealm.setCredentialsMatcher(hashedCredentialsMatcher()); return myShiroRealm; } } /** * 开启shiro aop注解支持. * 使用代理方式;所以需要开启代码支持; * @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开源插件 * @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 缓存 redis实现 * 使用的是shiro-redis开源插件 * @return */ public RedisCacheManager cacheManager(){ RedisCacheManager redisCacheManager = new RedisCacheManager(); redisCacheManager.setRedisManager(redisManager()); return redisCacheManager; } /** * RedisSessionDAO shiro sessionDao层的实现 通过redis * 使用的是shiro-redis开源插件 */ @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; } } ``` 总结原文地址: http://geeksblog.cc/sprigmvc2boot.html
