篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ssm框架中怎么让spring扫描多个包相关的知识,希望对你有一定的参考价值。
<context:component-scan base-package="com.test1,com.test2,com.test3" />扫描多个包用,号分隔即可
参考技术A 首先你为什么要使用spring呢? 使用spring的目的之一就是管理各种框架,让他们易于维护 spring能管理多达n中框架,其中多有的配置都是在spring中配置的本回答被提问者采纳 参考技术Bspring 配置扫描多个包,有时候我们希望不同功能类型的包放在不同的包下,这就需要
<context:component-scan base-package="com.wdh.controller" />
<context:component-scan base-package="com.wdh.listener" />
ssm框架整合
#弄了了我好久天的框架整合,今天终于弄好了。做一个小dome#
1、构建web工程
2、把需要的jar包导进去
3、springmvc 配置
<!-- spring 自动扫描 base-package下面的包或子包下面的Java文件,将扫描到有Spring的相关
注解的类注册为Spring的bean -->
<context:component-scan base-package="com.zspt.lab.web"></context:component-scan>
<!--设置配置方案 -->
<mvc:annotation-driven />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
4、db.properties 配置
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/admin_zspt
jdbc.username= #连接数据库的用户名
jdbc.password= #连接数据库的密码
5、applicationContext-dao.xml 配置
<!-- 加载配置文件 -->
<context:property-placeholder location="classpath:*.properties" />
<!-- 数据库连接池 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="driverClassName" value="${jdbc.driver}" />
<property name="maxActive" value="10" />
<property name="minIdle" value="5" />
</bean>
<!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 数据库连接池 -->
<property name="dataSource" ref="dataSource" />
<!-- 加载mybatis的全局配置文件 -->
<property name="configLocation" value="classpath:mybatis/sqlMapConfig.xml" />
</bean>
<!-- mapple扫描 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.zspt.lab.dao" />
</bean>
4、applicationContext-service.xml 配置
<context:component-scan base-package="com.zspt.lab.service.impl"/>
5、applicationContext-transaction.xml 配置
<!-- 事务管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 数据源 -->
<property name="dataSource" ref="dataSource" />
</bean>
6、web.xml配置
<!-- 加载spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- post乱码解决 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<!-- <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value>
</init-param> -->
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- springmvc的前端控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 如果不配置contextConfigLocation, 则默认加载:WEB-INF/servlet的名称+"-servlet.xml" -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 日志记录 -->
<context-param>
<!-- 日志配置文件路径 -->
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:log4j.properties</param-value>
</context-param>
<context-param>
<!-- 日志页面的刷新间隔 -->
<param-name>log4jRefreshInterval</param-name>
<param-value>6000</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
8、包装层model
#为了节省空间,构造方法和get/set方法就不写了
private String id;
private String username;
private String password;
9、web层
public class LoginController {
@Autowired
public IUserService userService;
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String toLogin(Model model) {
model.addAttribute("user", new User());
return "util/login";
}
@RequestMapping(value = "/login", method = RequestMethod.POST)
public String Login(Model model, RedirectAttributes redirectAttributes, User user) throws Exception {
if (userService.login(user) != null) {
redirectAttributes.addFlashAttribute("message", "登录成功");
} else {
redirectAttributes.addFlashAttribute("message", "登录失败");
}
model.addAttribute("user", user);
return "redirect:/transfer";
}
@RequestMapping(value = "/transfer")
public String transfer(Model model, User user) throws Exception {
model.addAttribute("user", user);
return "util/login";
}
}
10、业务层service
IUserService.java接口:
public User login(User user) throws Exception;
IUserServiceImp.java实现接口:
#记得加注解
@Service
public class IUserServiceImp implements IUserService {
@Autowired
private IUserDao userDao;
@Override
public User login(User user) throws Exception {
return userDao.login(user);
}
}
11、mapple代理的方法实现持久层dao
-
IUserDao.java 接口:
public User login(@Param(value="user")User user) throws Exception;
- IUserDao.xml: #xml文件的名称要和java文件名称一致
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zspt.lab.dao.IUserDao">
<sql id="aaa">
<if test="user!=null">
<if test="user.username!=null and user.password!=null">
username=#{user.username} AND password=#{user.password}
</if>
</if>
</sql>
<select id="login" resultType="user">
SELECT * FROM administrator
<where>
<include refid="aaa"></include>
</where>
</select>
</mapper>
12、log4j.properties
### 设置###
log4j.rootLogger = debug,stdout,D,E
### 输出到控制台 ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{1}:%L - %m%n
### 输出到日志文件 ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ./logs/log.log
log4j.appender.D.Append = true
## 输出DEBUG级别以上的日志
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
### 保存异常信息到单独文件 ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
## 异常日志文件名
log4j.appender.D.File = ./logs/error.log
log4j.appender.D.Append = true
## 只输出ERROR级别以上的日志!!!
log4j.appender.D.Threshold = ERROR
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
13、jsp页面
<form:form action="login" method="post" modelAttribute="user">
<table>
<tr>
<td>用户名</td>
<td><form:input path="username"></form:input></td>
</tr>
<tr>
<td>密码</td>
<td><form:password path="password"></form:password></td>
</tr>
<tr>
<td><input type="submit" value="登录"></td>
</tr>
<tr>
<td>${requestScope.message }</td>
</tr>
</table>
</form:form>
14、测试
用户名:zhangsan
密码:123465
数据库:
结果:
