SpringMVC的问题No mapping found for HTTP request with URI _springMVC

知识的领域是无限的,我们的学习也是无限期的。这篇文章主要讲述SpringMVC的问题No mapping found for HTTP request with URI相关的知识，希望能为你提供帮助。
做了一个屏蔽进数据库的操作:
Applicaition.xml配置:

< ?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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd"> < !-- 配置数据源，记得去掉myBatis-config.xml的数据源相关配置 --> < bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> < property name="driverClass" value="https://www.songbingjia.com/android/com.mysql.jdbc.Driver" /> < property name="jdbcUrl" value="https://www.songbingjia.com/android/jdbc:mysql://localhost:3306/mybatis2?useUnicode=true& amp; characterEncoding=UTF-8" /> < property name="user" value="https://www.songbingjia.com/android/root" /> < property name="password" value="https://www.songbingjia.com/android/123456" /> < /bean> < !-- 配置session工厂 --> < bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> < property name="dataSource" ref="dataSource" /> < property name="configLocation" value="https://www.songbingjia.com/android/classpath:mybatis-config.xml" /> < /bean> < !-- 配置事务管理器,管理数据源事务处理 --> < bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> < property name="dataSource" ref="dataSource" /> < /bean> < !-- 配置事务通知 --> < tx:advice id="advice" transaction-manager="transactionManager"> < tx:attributes> < !-- 默认只处理运行时异常，可加rollback-for="Exception/Throwable"等处理所有异常或包括错误 --> < tx:method name="insert*" propagation="REQUIRED" rollback-for="Exception" /> < tx:method name="update*" propagation="REQUIRED" rollback-for="Exception" /> < tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception" /> < tx:method name="*" propagation="SUPPORTS" /> < /tx:attributes> < /tx:advice> < !-- 配置SessionTemplate，已封装了繁琐的数据操作 --> < bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate" scope="prototype"> < constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory" /> < /bean> < !-- 配置切面织入的范围,后边要把事务边界定在service层 --> < aop:config> < aop:advisor advice-ref="advice" pointcut="execution(* com.liuyang.crm.service.Imp.*.*(..))" /> < /aop:config> < context:component-scan base-package="com.liuyang" /> < !--context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> < /context:component-scan --> < /beans>

【SpringMVC的问题No mapping found for HTTP request with URI】防止错误数据进入的屏蔽

< context:component-scan base-package="com.liuyang" /> < !--context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> < /context:component-scan -->

这里其实注销掉,也是好使的.加上了就出现文章上边的找不到url地址注入的错误.
spring-mvc.xml

< ?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd "> < !-- 同时开启json格式的支持 --> < mvc:annotation-driven> < /mvc:annotation-driven> < context:component-scan base-package="com.liuyang"> < context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> < context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" /> < /context:component-scan> < /beans>

这里配置屏蔽就可以,这样数据库同样不进错误数据.

< context:component-scan base-package="com.liuyang"> < context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> < context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" /> < /context:component-scan>
