手把手教你把sprigmvc项目转为springboot
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
org.springframework.boot spring-boot-starter-parent 1.5.9.RELEASE 复制代码 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 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
复制代码 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。
@SpringBootApplication//@ComponentScan({"com.cms.controller","com.cms.service","com.cms.dao"})public class Application extends 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); }}复制代码 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=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复制代码
4.使用@Configuration注入配置
- 注入mybatis配置,分页插件请自主选择
@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); }}复制代码 - 添加Interceptor配置,注意addInterceptor的顺序，不要搞乱了
@Configurationpublic class InterceptorConfiguration extends WebMvcConfigurerAdapter{ @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new LoginHandlerInterceptor()); }}复制代码 - 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。
@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 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; }}复制代码 总结
