RESTful风格的SSM框架搭建

1 使用idea编辑工具，maven项目构建工具搭建RESTful风格的java项目

 

2 进行项目配置

2.1 pom文件依赖

 4 问题小结

4.1 报错找不到applicationContext.xml 配置文件

 IOException parsing XML document from ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/applicationContext.xml]
解决方案：查看博文  关于“Could not open ServletContext resource [/WEB-INF/applicationContext.xml]”解决方案

4.2 报错org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):
解决方案
一般的原因是Mapper interface和xml文件的定义对应不上，需要检查包名，namespace，函数名称等能否对应上，需要比较细致的对比，

按以下步骤一一执行：

1：检查xml文件所在的package名称是否和interface对应的package名称一一对应

2：检查xml文件的namespace是否和xml文件的package名称一一对应

3：检查函数名称能否对应

但是博主在尝试以上方案之后仍然报错，在我查看了发布之后的源代码之后，发现*Mapper.xml文件并没有发布到目标文件中。我是使用maven 进行项目构建。修改pom.xmml文件，
在子项中添加

      
        src/main/resources
        true
        
          **/*.xml
        
      

      
        src/main/resources
        true
        
          **/*.properties
        
      

      
        src/main/resources
        
          **/*.properties
        
      

      
        src/main/java
        
          **/*.java
        
      

    

 

4.3 在请求中，获取string字符串中文乱码问题

解决方案，修改 springMVC.xml 配置文件，参考博客 SpringMVC源码总结（四）由StringHttpMessageConverter引出的客户端服务器端之间的乱码过程分析

        
            class="org.springframework.http.converter.StringHttpMessageConverter">
                "UTF-8"/>
            

        
    

 

4.4 处理返回类型是日期类型 Date

解决方案，修改 springMVC.xml 配置文件

        
            class="org.springframework.http.converter.StringHttpMessageConverter">
                "UTF-8"/>
            
            class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                "objectMapper">
                    class="com.fasterxml.jackson.databind.ObjectMapper">
                        "dateFormat">
                            class="java.text.SimpleDateFormat">
                                "java.lang.String" value="yyyy-MM-dd HH:mm:ss"/>
