  • 搭建JavaEE项目是遇到的几个问题

    问题描述:无法读取spring mvc的xsd文件

    参考http://eric-yan.iteye.com/blog/1908470

    schema_reference.4: Failed to read schema document 'http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd', because 1)  could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

    可能是eclipse的问题,代码没问题,只需要格式化一下,alt+s+f

    问题2:

    问题描述:No mapping found for HTTP request with URI

    参考:http://blog.sina.com.cn/s/blog_534f69a00101332u.html

    在springMVC配置文件中加入:<mvc:default-servlet-handler/>

    问题3:

    问题描述:Cannot create JDBC driver of class ''

    读取到的jdbc driver class name为空

    用Dbcp2的BasicDataSource,  配置如下:

    #driver=oracle.jdbc.OracleDriver
    driverClassName=oracle.jdbc.OracleDriver
    # driver.OracleDriver is compatible with oracle 8i
    url=jdbc:oracle:thin:@localhost:1521/xe
    # former name jdbc.user is i    nappropriate, use jdbc.username instead. BasicDataSource swallow a properties file that must conform to this naming.
    username=louis
    password=louis

    pro.load(DBUtil.class.getClassLoader().getResourceAsStream("/config/db/db.properties"));

    ds = BasicDataSourceFactory.createDataSource(pro);//得到一个连接池对象
    但是传入的参数pro中配置的driver而不是driverClassName而导致的问题
