Maven 引入SSM框架出現(xiàn)的異常之BindingException

IntelliJ IDEA 開發(fā)Spring-mvc +mybits 項目時，啟動tomcat后瀏覽器發(fā)送請求后收到了500服務(wù)器錯誤，錯誤如下：

HTTP Status 500 - Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.creditease.proxymanager.dao.ProxyInfoDAO.getProxyInfo

網(wǎng)上搜了一下，問題出在沒找到Mapper XML 文件
經(jīng)過多次嘗試發(fā)現(xiàn)出現(xiàn)這個問題的原因在于mybatis逆向生成mapper接口和mapper.xml文件放在了同一個文件夾中，在編譯打包時沒法加載mapper.xml文件。

兩種解決方式

• 方式一：

  • mapper接口和mapper.xml文件都在同一個路徑下時，在pom.xml文件添加如下內(nèi)容: 問題解決

    <build>
        <resources>
                <resource>
                        <directory>src/main/java</directory>
                        <includes>
                                <include>**/*.properties</include>
                                <include>**/*.xml</include>
                        </includes>
                        <filtering>false</filtering>
                </resource>
        </resources>
    </build>

• 方式二：
  • 將逆向生成的mapper和mapper.xml文件分別放在main/java和main/resources下同級包下，編譯打包時會把resources下的文件直接讀取進去，就不會出現(xiàn)找不到mapper.xml的錯誤
