Sprigmvc项目转为springboot

项目实战

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

  1. 删除之前的spring依赖，添加springboot依赖

            <executions>
                <execution>
                    <goals>

                </execution>
            </executions>
        </plugin>
    </plugins>

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);
    }
}

3.添加springboot配置文件

  1. 在resources下面添加application.properties文件
  2. 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

  1. 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);
        }
    }

  2. 添加Interceptor配置,注意addInterceptor的顺序，不要搞乱了

    7
    @Configuration
    public class InterceptorConfiguration extends WebMvcConfigurerAdapter{
        @Override
        public void addInterceptors(InterceptorRegistry registry) {
            registry.addInterceptor(new LoginHandlerInterceptor());
        }
    }

  3. 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。
