实现账号的启动禁止

EmployeeController 

@PutMappingpublic R<String> update(@RequestBody Employee employee){employeeService.updateById(employee);return R.success("员工信息修改成功");}

出错

解决

common目录下 引入JacksonObjectMapper

package com.itheima.reggie.common;import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.module.SimpleModule;

}

config目录WebMvcConfig类里面添加

 /*** 扩展mvc框架的消息转换器*/@Overrideprotected void extendMessageConverters(List<HttpMessageConverter<?>> converters) {log.info("扩展消息转换器...");//创建消息转换器对象MappingJackson2HttpMessageConverter messageConverter = new MappingJackson2HttpMessageConverter();//设置对象转换器，底层使用Jackson将Java对象转为jsonmessageConverter.setObjectMapper(new JacksonObjectMapper());//将上面的消息转换器对象追加到mvc框架的转换器集合中converters.add(0,messageConverter);}
