there is no ** getter for property 100C

这是我的controller:
@RequestMapping("/editFabricSubmit")
public String editFabricSubmit(HttpServletRequest request,
Fabric fabric,
MultipartFile fabric_pic) throws Exception{
String originalFilename = fabric_pic.getOriginalFilename();

        if(fabric_pic!=null && originalFilename!=null && originalFilename.length()>0){
        String pic_path = "D:\\pic\\";
         String newFileName = UUID.randomUUID() + originalFilename.substring(originalFilename.lastIndexOf("."));
        File newFile = new File(pic_path+newFileName);
        fabric_pic.transferTo(newFile);
        fabric.setPic(newFileName);

    }

fabricService.updateByPrimaryKeySelective(fabric);
return "success";
这是我的po:
private Integer id;

private String name;

private String compositions;

private Double baseprice;

private String yarncount;

private String density;

private String weight;

private String width;

private String pic;

private String supplierno;

private Double restmeter;
    这是我的mapper.
     <update id="updateByPrimaryKeySelective" parameterType="textile.ssm.po.Fabric" >
update fabric
set name = #{name,jdbcType=VARCHAR},
  compositions = #{compositions,jdbcType=VARCHAR},
  baseprice = #{baseprice,jdbcType=DOUBLE},
  yarncount = #{yarncount,jdbcType=VARCHAR},
  density = #{density,jdbcType=VARCHAR},
  weight = #{weight,jdbcType=VARCHAR},
  width = #{width,jdbcType=VARCHAR},
  pic = #{pic,jdbcType=VARCHAR}
  id = #{id,jdbcType=INTEGER},
  restmeter = #{restmeter,jdbcType=DOUBLE},

 where supplierno = #{supplierno,jdbcType=INTEGER}

为什么一直显示
there is no ** getter for property named 'technics' in 'class textile.ssm.po.Fabric'

6个回答

PS. jsp页面里面也没有这个technics

在测试时报错:There is no getter for property named'tj' in 'class java.lang.String'
 问题分析:Mybatis默认采用ONGL解析参数,所以会自动采用对象树的形式取string.tj值,引起报错。
 解决方法:  public ListmethodName(@Param(value="tj") String tj);说明参数......
答案就在这里:Mybatis-There is no getter for property named 'tj' in 'class

把jdbcType全去掉
比如:

        UPDATE  aaa set
        first=#{first},second=#{second},third=#{third}
        where id=#{id}

类型可以自动匹配

首先class textile.ssm.po.Fabric确实没有属性名为technics的get/set方法。这个technics应该不是你要的字段。你需要看看你的页面上是不是有什么控件name的名字是technics,导致说传到后台自动解析成这个Fabric对象的属性了,这需要小心的去查错。firebug看看urlpost了什么参数

居然是eclipse的缓存问题,
