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
<parent>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-starter-parentartifactId>
<version>1.5.9.RELEASEversion>

复制代码- 添加springboot构建插件
<plugins>
<plugin>
<groupId>org.apache.maven.pluginsgroupId>
<artifactId>maven-compiler-pluginartifactId>
<configuration>
<source>1.7source>
<target>1.7target>

复制代码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=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
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
@Configuration
public 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。
@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;
}
}
