springmvc项目转为springboot

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.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.9.RELEASE</version>

            <!-- 这个是剔除掉自带的 tomcat部署的-->

                <exclusion>

            <artifactId>tomcat-embed-jasper</artifactId>
        </dependency>
</dependencies>

添加springboot构建插件

<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>

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);
    }
}

添加springboot配置文件在resources下面添加application.properties文件
添加基本配置
```@SpringBootApplication
br/>在resources下面添加application.properties文件
添加基本配置
```@SpringBootApplication
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

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

@Configuration
public class InterceptorConfiguration extends 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。

@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<String,String> 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");

        //<!-- 过滤链定义，从上向下顺序执行，一般将 /**放在最为下边 -->:这是一个坑呢，一不小心代码就不好使了;
        //<!-- authc:所有url都必须认证通过才可以访问; anon:所有url都都可以匿名访问-->

        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());
