Spring注解扫描可以同时扫描多个包吗

Spring注解扫描:

<context:component-scan base-package="com.yh.login" />
我想问一下,可不可以同时扫描多个包?如果可以的话,请问怎么写?
比如是这样吗:
<context:component-scan base-package="com.yh.login,com.kf.pre" />
还是:
<context:component-scan base-package="com.yh.login" />
<context:component-scan base-package="com.kf.pre" />

4个回答

比如com.* 或者com.login.*

我以前用过,直接 就可以了,不过在要注入的地方要加上spring注入的标记。不过这样注入不怎么好控制

用×号代替。不过那是很早之前用过的,不知道现在还可不可以。,如果想控制好一点,就单个写。这样就不会有多余的注入。也就是像你第二种那样写,至于你那第一种,我个人没实验过

配置spring扫描器的一个疑问!
这是jeesite3里面配置的一段,扫描器的代码,为什么要这么配置,直接扫描不行吗? 为什么要让主容器和mvc容器,分别扫描不同的东西? ``` <!-- 使用Annotation自动注册Bean,解决事物失效问题:在主容器中不扫描@Controller注解,在SpringMvc中只扫描@Controller注解。 --> <context:component-scan base-package="com.thinkgem.jeesite"><!-- base-package 如果多个,用“,”分隔 --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ``` ``` <!-- 使用Annotation自动注册Bean,只扫描@Controller --> <context:component-scan base-package="com.thinkgem.jeesite" use-default-filters="false"><!-- base-package 如果多个,用“,”分隔 --> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ```
maven多模块下的spring 自动扫描
我创建的这个项目是maven工程,由一个父模块和四个子模块组成,controller是war包,其他几个模块都是jar包,所有配置文件都放在jslj-controller下的src/main/resources里面 ![图片说明](https://img-ask.csdn.net/upload/201704/14/1492156575_227142.png) 配置文件位置 ![图片说明](https://img-ask.csdn.net/upload/201704/14/1492156689_941688.png) applicationContext.xml扫描配置 ``` <!-- 扫描包 --> <context:component-scan base-package="cn.jscoin.jslj.*" /> ``` 我在jslj-controller里面用junit测试,mapper和service的注入都没有问题, ``` @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath*:applicationContext.xml") public class UserTest { @Autowired private UserMapper userMapper; @Autowired private UserService userService; @Test public void testAdd(){ User user = new User(); List<User> userAll = userMapper.queryUserAll(user); System.out.println(userAll.size()); } @Test public void testService(){ User user = new User(); List<User> userAll = userService.queryUserAll(user); System.out.println(userAll.size()); } } ``` 但是项目一跑起来就报错,注入失败。提示我不能注入cn.jscoin.jslj.service.UserService ,当时我的@service注解也加了,扫描也配置了 service位置 ![图片说明](https://img-ask.csdn.net/upload/201704/14/1492157192_572454.png) 错误提示 ``` SEVERE: StandardWrapper.Throwable org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private cn.jscoin.jslj.service.UserService cn.jscoin.jslj.controller.UserController.userService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [cn.jscoin.jslj.service.UserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Spring是怎么通过注解获取值?
有几种注解方式,是不是配置一个注解扫描就行了,注解扫描是JDK那个版本才有的,多分几个配置文件一个注解扫描就不行了
Spring框架中的Autowired注解,默认真的是按照ByType方式实现自动注入的吗?
在学习spring IOC的过程中,接触到@Autowired注解,资料上都是说默认是按照Bytype类型实现自动注入,但我的实际操作却发现是:先使用ByName,如果失败,再使用ByType。贴代码,求指点: Student类: ``` @Component public class Student { @Value("12") int age; @Value("lisa") String name; @Autowired School school; public Student(){} public Student(int age, String name, School school) { this.age = age; this.name = name; this.school = school; } @Override public String toString() { return "Student{" + "age=" + age + ", name='" + name + '\'' + ", school=" + school + '}'; } } ``` School类: ``` public class School { String name; String address; public School() { } public School(String name, String address) { this.name = name; this.address = address; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } ``` xml文件 ``` <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--配置注解扫描器,base-package表示注解所在的包,目的是告诉spring框架去扫描指定包的注解--> <context:component-scan base-package="com.aipande.bao1"/> <bean id="school" class="com.aipande.bao1.School"> <property name="name" value="武汉大学21"/> </bean> <bean id="school03" class="com.aipande.bao1.School"> <property name="name" value="武汉大学21"/> </bean> <bean id="school02" class="com.aipande.bao1.School"> <property name="name" value="武汉大学"/> </bean> </beans> ``` 测试类: ``` public class AppTest01 { public static void main(String[] args) { /* * 创建spring容器对象 * spring框架在加载xml文件并创建spring容器对象的同时, * 就会将xml文件中配置的bean对象(作用域为singleton)一同创建,并将这些对象放置在spring容器中。 * */ String config = "applicationContext.xml"; ApplicationContext ctx = new ClassPathXmlApplicationContext(config); //使用getBean()方法获取bean对象 Student stu = (Student) ctx.getBean("student"); System.out.println(stu); } } ``` 结果输出: ``` Student{age=12, name='lisa', school=School{name='武汉大学21', address='null'}} ``` 问题: 如果按照Bytype方式获取bean对象,那上面就应该报错啊,因为sprig容器中存在多个同源bean对象,但是没有报错,说明是按照byName的方式注入。后来我将xml文件中id为school的bean对象删除,就出现了错误提示,说明此时是按照byType的方式注入。因此我有上面的疑问,求解
maven项目 update project 后,Spring的注解不能使用,

关于ComponentScan注解看到一段解释,有疑问
今天学习权限管理框架第一次见到ComponentScan注解。查了关于它的教程文章其中有一段:“例如,如果你有个类用@Controller注解标识了,那么,如果不加上@ComponentScan,自动扫描该controller,那么该Controller就不会被spring扫描到,更不会装入spring容器中,因此你配置的这个Controller也没有意义。” ## **_那么我的问题是。我之前学做过一个spring boot+spring cloud搭建微服务的论坛项目。全程没有见过ComponentScan这个注解。但无疑Controller却有很多。这样一来上面那段话,我就不太明白了。请解惑_**
非web工程整合Spring,怎么使用@autowired
我在网上查了很多java整合Spring的例子,但大多数都是这main函数里面new ClassPathXmlApplicationContext("applicationContext.xml"); ,然后 getBean给某个没有实例化的变量,而且@autowired没有作用,这样导致了我在每个需要注入的地方都要去写一遍 ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml"); jdbcTemplate=(JdbcTemplate)ac.getBean("jdbcTemplate"); 怎么做到 就是普通的java工程和web里面的一样,只要扫描一次配置文件,可以各种使用@autowried注解。

请教spring 3+mybatis整合出错问题
spring 3+mybatis3+spring security整合,我的包和层次结构如下:采用的是按照模块分层, 每层有dao,sevrice,web三个目录,所有的实体类放在model文件夹中 security包中,有dao,service,web三个目录,其中 SecurityDao.java @MyBatisDao public interface SecurityDao extends BaseMapper<Security> { // 获得群组usergroups对应的权限 public List<Security> getGroupResources(); } SecurityService.java接口 ``` public interface SecurityService extends BaseService<Security> { public List<Security> getGroupResources(); } ``` SecurityServiceImpl .java @Service(value = "securityService") public class SecurityServiceImpl implements SecurityService { @Autowired private SecurityDao securityDao; // 获得群组usergroups对应的权限 public List<Security> getGroupResources() { return securityDao.getGroupResources(); } } MyBatisDao.java ``` /** * 标识MyBatis的DAO,方便{@link org.mybatis.spring.mapper.MapperScannerConfigurer}的扫描。 * */ @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.TYPE) @Documented @Component public @interface MyBatisDao { /** * The value may indicate a suggestion for a logical component name, * to be turned into a Spring bean in case of an autodetected component. * @return the suggested component name, if any */ String value() default ""; } ``` 然后系统有一个model的包,存放各模块的实体类这里有security.java,get/set就省略 了, 然后在maven的resource下建立文件src\resource\mappings\modules\security\SecurityDao.xml ``` <mapper namespace="com.liao.modules.core.security.dao.SecurityDao"> <resultMap id="getUserInfoMap" type="Security"> <result property="userid" column="userid"/> <result property="username" column="username"/> <result property="password" column="password"/> <result property="enabled" column="enabled"/> </resultMap> <select id="getGroupResources" resultType="Security"> select g.role_name roleName,a.url resourceValue from usergroups g join groupauthority_mapping ga on g.groupid=ga.groupid join authority a on ga.authorityid=a.authorityid </select> ``` spring-mvc.xml: ``` <!-- 自动扫描bean,把作了注解的类转换为bean --> <context:component-scan base-package="com.liao" > <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ``` 其他mvc配置省略 spring-context-application.xml: ``` <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动匹配Mapper映射文件 --> <property name="mapperLocations" value="classpath:mappings/**/*.xml"/> <property name="typeAliasesPackage" value="com.liao.model"/> <property name="configLocation" value="classpath:/mybatis-config.xml"></property> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.liao" /> <property name="annotationClass" value="com.itownet.isms.core.annotation.MyBatisDao"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> <!-- 事务配置 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> ``` mybatis-config.xml: ``` <configuration> <!-- 全局参数 --> <settings> <!-- 使全局的映射器启用或禁用缓存。 --> <setting name="cacheEnabled" value="true"/> <!-- 全局启用或禁用延迟加载。当禁用时,所有关联对象都会即时加载。 --> <setting name="lazyLoadingEnabled" value="true"/> <!-- 当启用时,有延迟加载属性的对象在被调用时将会完全加载任意属性。否则,每种属性将会按需要加载。 --> <setting name="aggressiveLazyLoading" value="true"/> <!-- 是否允许单条sql 返回多个数据集 (取决于驱动的兼容性) default:true --> <setting name="multipleResultSetsEnabled" value="true"/> <!-- 是否可以使用列的别名 (取决于驱动的兼容性) default:true --> <setting name="useColumnLabel" value="true"/> <!-- 允许JDBC 生成主键。需要驱动器支持。如果设为了true,这个设置将强制使用被生成的主键,有一些驱动器不兼容不过仍然可以执行。 default:false --> <setting name="useGeneratedKeys" value="false"/> <!-- 指定 MyBatis 如何自动映射 数据基表的列 NONE:不隐射 PARTIAL:部分 FULL:全部 --> <setting name="autoMappingBehavior" value="PARTIAL"/> <!-- 这是默认的执行类型 (SIMPLE: 简单; REUSE: 执行器可能重复使用prepared statements语句;BATCH: 执行器可以重复执行语句和批量更新) --> <setting name="defaultExecutorType" value="SIMPLE"/> <!-- 使用驼峰命名法转换字段。 --> <setting name="mapUnderscoreToCamelCase" value="true"/> <!-- 设置本地缓存范围 session:就会有数据的共享 statement:语句范围 (这样就不会有数据的共享 ) defalut:session --> <setting name="localCacheScope" value="SESSION"/> <!-- 设置但JDBC类型为空时,某些驱动程序 要指定值,default:OTHER,插入空值时不需要指定类型 --> <setting name="jdbcTypeForNull" value="NULL"/> </settings> ``` 在spring secrutiy中,调用 ``` public class DefinitionSourceFactoryBean implements FilterInvocationSecurityMetadataSource { @Autowired private SecurityService securityService; public void findResources() { List<Security> resourcesgroup = securityService.getGroupResources(); } } ``` 这个时候在运行securityService.getGroupResources();,说: mybatis,Invalid bound statement (not found): com.liao.core.security.dao.SecurityDao.getGroupResources 编译后,已经检查过,maoper.xml在web-inf\classes目录下了,为什么呢?

System.out.println(getSessionFactory().getCurrentSession().beginTransaction().isActive()); } } 整体代码是这样的,在运行daoImpl.java中test()方法的时候执行第一条SQL时会提交事物,直接修改数据库中的值,执行第二条SQL时会报错,理论上应该都不提交事物。但实际上第一条执行了之后就提交事物了,不知道是我框架问题还是我写的问题,求大神帮忙指出问题所在。万分感谢! ```

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 *

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
