Validate JsonMapper and ApplicationContextHelper

 

TestController

 @RequestMapping("/select")
    @ResponseBody
    public JsonData validate (TestVo vo) {

        SysAclModuleMapper moduleMapper = ApplicationContextHelper.popBean(SysAclModuleMapper.class);
        SysAclModule module = moduleMapper.selectByPrimaryKey(1);

        return JsonData.success(module);
    }

Run tomcat, the result

yintingtingdeMacBook-Pro:generator yintingting$ curl http://localhost:8080/test/validate1.json

{"ret":false,"msg":"{str=cannot be empty, id=id cannot be empty, msg=cannot be empty}","data":null} yintingtingdeMacBook-Pro:generator yintingting$ 

 

When using mybatis, note that mybatis and mybatis-spring must correspond. When mybatis version is above 3.4.0, mybatis-spring needs to be above 1.3.0
