springboot将Controller包、Mapper(DAO)包与启动类放置于同一包内仍扫描不到。

用springboot开发web服务端,同时使用mybatis、swagger。项目目录如下:
图片说明

首先是DAO包中的mapper文件无法扫描到,mybatis-config中已经相关配置:

    <mappers>
        <mapper resource="Mapper/*.xml" />
        <package name="com.storm.datemanager.DAO"/>
    </mappers>

运行失败后报如下错误:

Description:

Field userInfoMapper in com.storm.datemanager.Service.UserInfoService required a bean of type 'com.storm.datemanager.DAO.UserInfoMapper' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.storm.datemanager.DAO.UserInfoMapper' in your configuration.

其次,在通过swagger显示controller时为空,url访问controller时报404错误,应该也是没有扫描到Controller文件夹controller代码如下

@CrossOrigin(origins = "*")
@RestController
@RequestMapping("/admin")
@Api(tags = "管理员模块")
public class AdminController {

    @Autowired
    private UserInfoService userInfoService;

    @ApiOperation(value = "获取所有用户")
    @GetMapping("/fetchAllUsers")
    public Result<List<UserInfo>> fetchAllUsers(@ApiParam("管理员ID")@RequestParam String Id){
        return userInfoService.fetchAllUser(Id);
    }
}

后想再次使用componentscan时,仍然报错找不到DAO中的mapper

@SpringBootApplication
@EnableSwagger2
@ComponentScans(value = {
        @ComponentScan("com.storm.datemanager.DAO"),
        @ComponentScan("com.storm.datemanager.Controller")
})
public class DatemanagerApplication {

    public static void main(String[] args) {
        SpringApplication.run(DatemanagerApplication.class, args);
    }

}

据说springboot的包扫描机制是扫描启动类所在的包以及其子包的所有文件,那么理论上来说这样的目录结构是不需要ComponentScan的,可是为何ComponentScan mapper文件可行,而ComponentScans两个文件夹就不可以?
求大佬解惑

3个回答

mapper的位置填写方式不对吧,是不是少了 classpath前缀

pom文件加上这句话试试




src/main/java

**/*.xml

true

springboot 启动类打相关注解;
//这里打上相关要扫描的包
@SpringBootApplication(scanBasePackages = "com.xxx")
// 扫描Mapper接口的路径
@MapperScan("com.xxx.mapper")

springboot项目controller注入失败,空指针;单元测试没有问题

Springboot启动报错 一个是找不到url 一个是找不到dao

## 之前一直启动都没有问题,今天突然发现启动不了 ![图片说明](https://img-ask.csdn.net/upload/201910/10/1570671612_490949.jpg) ## 然后我把启动的位置改成@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) ``` package com.mall.shopping.demo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import

spring整合使用mybatis的接口,但使用时显示在spring容器内找不到dao的接口对象。

本来已经整合了spring和springmvc,然后我再添加了mybatis的依赖,数据库的配置等等。在test类里mybatis可以单独运作。但是和spring整合的时候就出现问题. 这是我的目录结构 ![图片说明](https://img-ask.csdn.net/upload/202002/11/1581431166_377484.png) 我的dao中的类如下 ``` @Repository public interface IAccountDao { @Select("select * from account") List<Account> findAll(); @Insert("insert into account(name,money) values (#{name},#{money})") void saveAccount(Account account); } ``` service中的类如下 ``` @Service("accountService") public class AccountServiceImpl implements IAccountService { @Autowired private IAccountDao accountDao; @Override public List<Account> findAll() { System.out.println("findAll_service"); return accountDao.findAll(); } @Override public void saveAccount(Account account) { System.out.println("saveAccount_service"); accountDao.saveAccount(account); } } ``` 而且我的spring的配置文件已经按照教程中那样引入了mybatis的工厂什么的 ``` <?xml version="1.0" encoding="UTF-8"?> <beans 一堆约束省略了> <context:component-scan base-package="com.HSY"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 整合Mybatis--> <!-- 配置C3P0的连接池对象 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/ssm" /> <property name="username" value="root" /> <property name="password" value="123456" /> </bean> <!-- 配置SqlSession的工厂 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 配置扫描dao的包--> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.HSY.dao"/> </bean> </beans> ``` SqlMapConfig的数据库配置也配了,但是最后仍然报错 ``` beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.HSY.dao.IAccountDao' available: expected at least 1 bean which qualifies as autowire candidate.

Sping Boot注入接口失败

![图片说明](https://img-ask.csdn.net/upload/201804/21/1524291637_361310.png) 项目结构应该是正确的。 ``` @Repository public interface UserDao { public User getById(int id); } ``` Dao层的代码,使用接口。 @Service ``` @Service public class UserService { @Autowired UserDao userDao; public User getById(int id) { return userDao.getById(id); } } ``` service层代码。 controller层注入service。 启动spring boot后会提示dao层没有扫描到,如果@ComponentScan dao层的话,会提示service层注入失败,求解。

spring不同包下的bean命名冲突,哪位大神能帮忙解决下。

项目分为多个模块,在eclipse中正常启动。在idea中启动项目,遇到了如下的问题:java.lang.IllegalStateException: Annotation-specified bean name 'dictOrganizationMapper' for bean class [msun.server.mapper.hbp.DictOrganizationMapper] conflicts with existing, non-compatible bean definition of same name and class [msun.server.mapper.DictOrganizationMapper](冲突的两个类属于不同的模块) (不能通过改bean名称的方式来解决问题)

NettyServer注入失败,无法交给IOC托管

netty服务端需要跟DB交互 ``` @Component("nettyServer") public class MyServerHandler extends SimpleChannelInboundHandler<String> { @Autowired private CoreUserMapper userMapper; @Autowired private CoreRounduserMapper rounduserMapper; ``` 此处的俩mapper都为null 但是我在MyServerHandler里写个测试方法引用mapper内的方法,新建一个Controller然后@autowired注入这个MyServerHandler,断点进来这个mapper就不是空了,所以不是扫描路径的问题,我试过用service注解和@Component注解,还有在xml里bean注入都无法单独托管这个MyServerHandler

spring boot注入jar包中的接口总是提示that could not be found

首先是在spring boot项目中注入的jar包中的接口 ``` @Controller public class MessageTransferStationController { @Autowired private MessageClient messageClient; } ``` 其次,jar包中的MessageClient的源码 ``` public interface MessageClient { } ``` MessageClient分别有三个实现类 ``` public class CoreMessageClient implements MessageClient {} @Component public class SpringMessageClientImpl extends CoreMessageClient implements MessageClient {} public class Spring2MessageClientImpl extends CoreMessageClient implements MessageClient {} ``` 当我在spring boot项目中注入MessageClient接口的时候,启动报错: 017-06-12 15:06:53.281 WARN 9780 --- [ main] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'messageTransferStationController': Unsatisfied dependency expressed through field 'messageClient'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.sinosoft.messageclient.MessageClient' available: expected at least 1 bean which qualifies as autowire candidate.

Action: Consider defining a bean of type 'com.sinosoft.messageclient.MessageClient' in your configuration. Process finished with exit code 1 --- 请问各位大佬,为什么MessageClient为什么不能注入,我猜想过MessageClient的实现类没有被Spring管理,我看了jar包中源码有一个实现类加上了@Component注解 求教各位大佬,这是什么原因引起的? 注:引用jar包中的其它接口也测试过了,同样的错误,也就是说引用的这个jar包中的所有接口都没有被spring管理,或者没有扫描。

maxElementsInMemory==内存缓存中最多可以存放的元素数量,若放入Cache中的元素超过这个数值,则有以下两种情况 * 1)若overflowToDisk=true,则会将Cache中多出的元素放入磁盘文件中 * 2)若overflowToDisk=false,则根据memoryStoreEvictionPolicy策略替换Cache中原有的元素 * eternal==============缓存中对象是否永久有效,即是否永驻内存,true时将忽略timeToIdleSeconds和timeToLiveSeconds * timeToIdleSeconds====缓存数据在失效前的允许闲置时间(单位:秒),仅当eternal=false时使用,默认值是0表示可闲置时间无穷大,此为可选属性 * 即访问这个cache中元素的最大间隔时间,若超过这个时间没有访问此Cache中的某个元素,那么此元素将被从Cache中清除 * timeToLiveSeconds====缓存数据在失效前的允许存活时间(单位:秒),仅当eternal=false时使用,默认值是0表示可存活时间无穷大 * 即Cache中的某元素从创建到清楚的生存时间,也就是说从创建开始计时,当超过这个时间时,此元素将从Cache中清除 * overflowToDisk=======内存不足时,是否启用磁盘缓存(即内存中对象数量达到maxElementsInMemory时,Ehcache会将对象写到磁盘中) * 会根据标签中path值查找对应的属性值,写入磁盘的文件会放在path文件夹下,文件的名称是cache的名称,后缀名是data * diskPersistent=======是否持久化磁盘缓存,当这个属性的值为true时,系统在初始化时会在磁盘中查找文件名为cache名称,后缀名为index的文件 * 这个文件中存放了已经持久化在磁盘中的cache的index,找到后会把cache加载到内存 * 要想把cache真正持久化到磁盘,写程序时注意执行net.sf.ehcache.Cache.put(Element element)后要调用flush()方法 * diskExpiryThreadIntervalSeconds==磁盘缓存的清理线程运行间隔,默认是120秒 * diskSpoolBufferSizeMB============设置DiskStore(磁盘缓存)的缓存区大小,默认是30MB * memoryStoreEvictionPolicy========内存存储与释放策略,即达到maxElementsInMemory限制时,Ehcache会根据指定策略清理内存 * 共有三种策略,分别为LRU(最近最少使用)、LFU(最常用的)、FIFO(先进先出)
