Sprigmvc项目转为springboot

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

  2. 添加springboot构建插件

    <goals>
    <goal>repackage</goal>
    </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

    1

    3
    4
    5
    6
    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。
