SSM框架中怎么理解controller和service层的关系。

SSM框架前端管理员A要修改一个实体对象,应该用哪个controller处理(具体对象的?还是user的?),如果同时修改多个呢?如果是user的这个具体的修改操作应该放到谁的service层?

3个回答

再理解一下面向对象,根据你第一句话,这应该是前端管理员所具有的一个功能,那么自然要使用user的controller处理了,在其中调用user的service中对应的方法,在这个service的方法中,你可以再调用那个被修改的对象的service中的方法实现具体的修改功能

一般来说,controller不应该放太多的业务逻辑代码,也就是说,修改实体应该放在service。修改多个实体,那么可以考虑对 IList<User> 操作。

qq_38909690 这个我知道。。。可能我表达有问题,我的意思就这个接收前端参数然后调用service的controller应该是谁?

具体对象,修改多个把对象放到list里,放到user的service层

SSM框架,所有的controller都调用同一个service会不会出问题?

SSM框架,为了方便把所有的service抽取到一个公共的service,包括service的实现,Dao,Dao的实现。所有的增删改查,分页等方法全在里面。通过方法参数区分mapper,查询字段都是通过参数动态设置的。用了几个月暂时没出现大问题,我想问下,这种方式最终会不会出现某些问题?之前是一个 controller对应一个service对应一个(或多个)Dao,现在我弄的是多个controller对应一个service对应一个Dao。

使用SSM框架配置式开发(不用注解),为何Service中无法注入Dao?

我用Intellij Idea开发的,所以配置文件中出错会标识红色,spring-service.xml中的ref="IStudentDao"部分出错。 另外我用Maven做的项目管理,不知道是不是配置文件放置的路径有问题。附上我的项目目录结构:![图片说明](https://img-ask.csdn.net/upload/201704/17/1492434652_95958.png) 部署到Tomcat上启动后,报No adapter for handler [com.bruceliao.controller.StudentController@12bc3bf8]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler Mybatis配置文件: ``` <configuration> <!--别名--> <typeAliases> <package name="com.bruceliao.beans"/> </typeAliases> <!--Mapper的位置--> <mappers> <package name="com.bruceliao.dao"/> </mappers> </configuration> ``` Spring配置文件: spring-mybatis.xml ``` <!--注册sqlSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="configLocation" value="classpath:mybatis.xml"/> <property name="dataSource" ref="dataSource"/> </bean> <!--生成Dao代理对象--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <property name="basePackage" value="com.bruceliao.dao"/> </bean> ``` spring-service.xml ``` <!--注册Service--> <bean id="studentService" class="com.bruceliao.service.impl.StudentServiceImpl"> <property name="studentDao" ref="IStudentDao"/> </bean> ``` spring-mvc.xml ``` <bean id="/view/login.do" class="com.bruceliao.controller.StudentController"> <property name="studentService" ref="studentService"/> </bean> ``` ![图片说明](https://img-ask.csdn.net/upload/201704/17/1492435263_528738.png)

SSM框架,页面静置一段时间后,执行查询,从controller调用service函数没有立刻执行,之间隔了约20秒,怎么解决?

如题,查询页面静置一段时间后,大概5分钟,再次执行查询时,service函数没有立刻执行,可能是什么原因导致的?怎么解决? 连接的数据库是Oracle。框架用的是SSM。 Controller: ``` @Controller @RequestMapping("/tcczbquery") public class ZBQueryController { @Autowired private ZBQueryService zbQueryService; @RequestMapping("/tccqueryzb.do") @ResponseBody public JSONObject queryZB(@RequestBody QueryCondition queryCondition){ System.out.println("开始----" + System.currentTimeMillis()); System.out.println(queryCondition); System.out.println("调用queryTargets----" + System.currentTimeMillis()); Result result = zbQueryService.queryTargets(queryCondition); System.out.println(JSON.toJSONString(result)); return JSON.parseObject(JSON.toJSONString(result)); } } ``` Service: ``` @Service @Transactional public class ZBQueryServiceImpl implements ZBQueryService { @Autowired private ZBConfigMapper zbConfigMapper; @Autowired private ZBQueryOrclMapper zbQueryOrclMapper; @Autowired private ZBQueryStsMapper zbQueryStsMapper; @Override public Result queryTargets(QueryCondition condition) { System.out.println("运行queryTargets----" + System.currentTimeMillis()); Result result = new Result(); return result; } } ``` 运行截图: ![图片说明](https://img-ask.csdn.net/upload/201910/24/1571896107_804342.png)

Controller Service Dao 关系

``` public class UserController extends WAFController<UserService> { } ``` UserController.java ``` public class UserService extends WAFService<UserDAO> { } ``` UserService.java ``` public class UserDAO extends DAOSupport { } ``` UserDAO.java ``` public abstract class WAFController<T extends WAFService<?>> extends BaseController<T> { } ``` WAFController.java ``` public abstract class WAFService<T extends DAOSupport> extends BaseService<T> { } ``` WAFService.java ``` public abstract class BaseController<T extends BaseService<?>> { } ``` BaseController.java ``` public abstract class BaseService<T extends DAOSupport> { } ``` BaseService.java ``` public class DAOSupport implements DAO { } ``` DAOSupport.java ``` public interface DAO { } ``` DAO.java

SSM框架controller函数参数值无法传给service函数

username和password有值也可以传递,可是进不了service函数 ![代码1](https://img-ask.csdn.net/upload/202003/31/1585628362_335875.png) ![控制台1](https://img-ask.csdn.net/upload/202003/31/1585628639_89064.png) 直接赋值没问题 ![代码2](https://img-ask.csdn.net/upload/202003/31/1585628690_839270.png) ![控制台2](https://img-ask.csdn.net/upload/202003/31/1585628754_887146.png) 传给User也没问题 ![代码3](https://img-ask.csdn.net/upload/202003/31/1585628895_280679.png) ![代码4](https://img-ask.csdn.net/upload/202003/31/1585628914_978347.png) 连这样也不行 ![代码4](https://img-ask.csdn.net/upload/202003/31/1585632608_945978.png) ![控制台4](https://img-ask.csdn.net/upload/202003/31/1585632627_419314.png) 就好像 ``` public User login(String username,String password) ``` 中的两个参数绝对进不了 ``` userService.login(username,password) ``` 函数中一样 为什么会这样!我真是想不通呀(无maven)

ssm框架,页面跳转,执行到controller就不执行了

![图片说明](https://img-ask.csdn.net/upload/201911/09/1573280738_235403.png) ![图片说明](https://img-ask.csdn.net/upload/201911/08/1573213189_263648.png)![图片说明](https://img-ask.csdn.net/upload/201911/08/1573213201_303403.png) 进入了userlogin.action了,就不往下执行了。找不到WEB-INF/jsp下的文件,可是我的文件就放在这里边

mybatis可以生成controller+service+mapper+bean+xml吗?

今天听朋友说,mybatis可以生成controller+service,一个持久层框架为什么要生成这两个东西? 网上就有一个 > https://www.baidu.com/link?url=-n6ngFKgH4o5o5QNY7JE3vCF5afvbKhjFNXWu9sqCIAkGX7-NaLLWZ1egrFfS4Xu&wd=&eqid=a734dedf0001be600000000258214d10 但是看起来不是通过generatorConfig.xml来逆向生成的,应该不是官方的方案吧

关于ssm框架中jsp往后台传值的问题

我前台获取到一个字符串 111111#\n22222 在后台获取的时候 #和#号后面的都没有了。。 用的是location.href="xx.html?xxx="+encodeURI(encodeURI(xxx)); 但是传 类似 111111.*.*\n22222 后台获取正常。。。

使用maven搭建的ssm框架能够访问jsp页面但是就是无法访问controller层,代码如下

controller层是这样的 @Controller @RequestMapping("web_User") public class UserController { private static final Logger logger = Logger.getLogger(UserController.class); @Resource private UserService userService; /** * 获取具体用户信息 * */ @RequestMapping(value = { "getUserById_test" }, method = { RequestMethod.POST }) public @ResponseBody Map<String,Object> getVideoById(@RequestParam long id) { User user = userService.finduserById(id); Map<String, Object> map = new HashMap<String, Object>(); map.put("result", user); return map; } } applicationcontext是这样的 <?xml version="1.0" encoding="UTF-8"?>
