关于SpringBoot+myBatis实体的字段返回前端后格式变化的问题

我的架构是 springBoot(1.5.9)+myBatis ,连接池用的是阿里的druid,以下是配置信息:

现在遇到的问题是:
实体类中的格式 返回到页面后,字段格式变化了,如下图:
实体:
图片说明

数据库:

返回到页面后的值(controller注解了@RestController):
图片说明

第二个字母 应该是大写C 结果变成了小写c。

而且有个现象是:
如果你的字段是 sName 那么前端拿到的是sname
如果你的字段是seName 那么前端拿到的就是seName 不会变化

也就是说 如果驼峰前字母是2个或2个以上 他就按照原来的格式了,不知道具体是什么原因,求大佬教导。

ps:
我试过很多种方法,只有一种有效果 就是给字段注解 @JsonProperty
但是这种方法会造成我的返回值里会有2个 sname 一个是sname 一个是sName 2个字段都是同样的值 给我一种复制的感觉。。

我找到了两个回答,应该能说明你这个问题的,你看下:

你可以把get/set方法改成这样子的试一试: getsName/setsName

qq_34967750
qq_34967750 你没理解我的意思。。
接近 2 年之前 回复

能看看你controller对应方法的代码吗?

一般情况下,属性的命名不应该使用第二个字母大写的方式,你可以看看你的getter/sertter方法就知道问题所在了,,

I'm sorry 我觉得你应该好好看看java的命名规范:
javabean命名要避免第二个字母大写,否在set,get的时候 它会有问题,会映射不上。反正各种问题,

拿走不谢^_^

Springboot下mybatis如何配置databaseId
Springboot设置了mybatis.config-location,然后在mybatis-config.xml下配置了databaseIdProvider type="DB_VENDOR" <databaseIdProvider type="DB_VENDOR"> <property name="DB2" value="db2"/> <property name="Oracle" value="oracle" /> <property name="Adaptive Server Enterprise" value="sybase"/> <property name="MySQL" value="mysql" /> </databaseIdProvider> 但是不会生效,调试发现初始化时由于Database是在application.propertities下定义的,mybatis初始化时会检测Environment是否为null,为null则不设置databaseId,在Spring下知道如何配置,但是SpringBoot下搞不定,求大神指点
SpringBoot集成Mybatis遇到问题
小白一个,第一次使用springboot,想用mybatis来做dao层框架,按网上资料进行了一下配置但是出现了一个错误,我不知道我的配置错在哪儿,麻烦大神帮忙指导一下,谢谢: application.properties配置如下: mybatis.mapper-locations=classpath:mapper/mapper/*Mapper.xml mybatis.config-location=classpath:mapper/sqlMapConfig.xml spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.username=root spring.datasource.password=root 接着是sqlMapConfig.xml: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> </configuration> 然后是mapp.xml的配置 <mapper namespace="com.tky.test.dao.UserMapper"> <select id="getUser" resultType="com.tky.test.emit.User"> select * from user </select> </mapper> sercive层代码如下: package com.tky.test.service; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.tky.test.dao.UserMapper; import com.tky.test.emit.User; @Service(value="userService") public class UserServiceImpl implements UserService{ @Resource private UserMapper userMapper; @Override public List<User> findUser() { List<User> findAll = userMapper.findAll(); return findAll; } } 然后是Mapper接口的代码: package com.tky.test.dao; import java.util.List; import com.tky.test.emit.User; public interface UserMapper { public List<User> findAll(); } 在下面是controller层的: @RestController(value="userController") public class UserController { @Resource private UserService userService; @RequestMapping("my") public List<User> getMy(){ List<User> findUser = userService.findUser(); return findUser; } } 最后是springboot的主函数代码: import org.apache.ibatis.session.SqlSessionFactory; import org.mybatis.spring.SqlSessionFactoryBean; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.Bean; @SpringBootApplication @MapperScan(value="com.tky.test.dao") public class Driver { public static void main(String[] args) { //项目入口 SpringApplication.run(Driver.class,args); } @Bean public SqlSessionFactory sessionFactory() throws Exception{ SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBean().getObject(); return sqlSessionFactory; } } 最后的报错信息很长是这样的: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userMapper' defined in file [D:\work\tky_workspace\Test_SpringBoot\target\classes\com\tky\test\dao\UserMapper.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in com.tky.test.Driver: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sessionFactory' threw exception; nested exception is java.lang.IllegalArgumentException: Property 'dataSource' is required 有没有大神能看明白的帮忙指导一下,谢谢
springboot整合mybatis中逆向生成的xxxExample文件
最近整合springboot+mybatis时候遇见两个问题, 一开始我用springboot2.1版本mysql8版本死活运行不了,一个劲找不到service的bean。 然后我换成了springboot2.0版本和mysql5.1版本就可以运行。 另外我按照网上的那些教材,发现当生成的model只有xxx一个时候,就没问题,而同时生成xxx和xxxExample时候,运行就会报错,说mapper无法生成bean,而生成时候取消Example就能正常运行。 没找到原因,头大。

Springboot+Mybatis接收react前端POST请求查询不到结果
后台可以收到请求的json数据,用相同的数据单独测试后台也可以搜到结果。但是直接从react前端发送请求,搜索结果就为空。 单独测试后台StaffManagementController,main方法中创建staffAO对象department=chemistry, 可以搜索到staffVOList.size=6个结果。从react前端表单department输入chemistry,发送POST请求,搜索到结果却是staffVOList.size=0个结果. esclipse后台console也显示staffAO.department=chemistry,说明前端请求可以正确接收。但是不知道为什么搜索不到结果。问题应该出在后台,但是完全想不出还哪里能出问题。。 下面是controller,function,mapper代码。希望有高手指教,非常感谢! ``` @RestController @RequestMapping("/api") public class StaffManagementController { private StaffManagementFunction function; @PostMapping("staffs/find") List<StaffManagementViewObject> getStaffByKeys(@Valid @RequestBody StaffManagementArgumentObject staffAO) throws Exception { log.info("Request to search for staff: {}", staffAO); List<StaffManagementViewObject> staffs = function.findStaffByKeys(staffAO); if (staffs == null) { new ResponseEntity<>(HttpStatus.NOT_FOUND); } return staffs; ``` ``` @Service public class StaffManagementFunctionImpl implements StaffManagementFunction{ @Override public List<StaffManagementViewObject> findStaffByKeys(StaffManagementArgumentObject staffManagementArgumentObject) throws Exception { SqlSession session = MyBatisUtil.getSession(); StaffManagementMapper smMapper = session.getMapper(StaffManagementMapper.class); if(staffManagementArgumentObject==null){ throw new IllegalArgumentException("argumentObject cannot be blank"); } String genderInput = staffManagementArgumentObject.getGender(); String gender= (genderInput==null)?null:(genderInput=="male")?"true":"false"; staffManagementArgumentObject.setGender(gender); List<StaffManagement> staffList = smMapper.selectKeysLike(staffManagementArgumentObject); MyBatisUtil.closeSession(); List<StaffManagementViewObject> staffVOList = new ArrayList<StaffManagementViewObject> (); for(int i = 0 ; i < staffList.size() ; i++) { StaffManagement staff = staffList.get(i); String genderVO = AssertThrowUtil.parseGenderToString(staff.getGender()); String yearOfGraduationVO = AssertThrowUtil.parseYearToString(staff.getYear StaffManagementViewObject staffVO = new StaffManagementViewObject(); staffVO.setId(staff.getId()); staffVO.setName(staff.getName()); staffVO.setGender(genderVO); staffVO.setDepartment(staff.getDepartment()); staffVO.setYearOfGraduation(yearOfGraduation); staffVOList.add(staffVO); } return staffVOList; } ``` ``` StaffManagementMapper.xml <select id="selectKeysLike" parameterType="com.springboot.demo.controller.StaffManagementArgumentObject" resultMap="BaseResultMap"> select * from staff_management where Name like '%${name}%' AND Gender like '%${gender}%' AND Department like '%${department}%' AND Position like '%${position}%' AND Year_of_graduation like '%${yearOfGraduation}%' </select> ```

源码阅读(19):Java中主要的Map结构——HashMap容器(下1)
HashMap容器从字面的理解就是,基于Hash算法构造的Map容器。从数据结构的知识体系来说,HashMap容器是散列表在Java中的具体表达(并非线性表结构)。具体来说就是,利用K-V键值对中键对象的某个属性(默认使用该对象的“内存起始位置”这一属性)作为计算依据进行哈希计算(调用hashCode方法),然后再以计算后的返回值为依据,将当前K-V键值对在符合HashMap容器构造原则的基础上,放置到HashMap容器的某个位置上,且这个位置和之前添加的K-V键值对的存储位置完全独立,不一定构成连续的存储

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

关于SQL和ORM的争论,永远都不会终止,我也一直在思考这个问题。昨天又跟群里的小伙伴进行了一番讨论,感触还是有一些,于是就有了今天这篇文。 声明:本文不会下关于Mybatis和JPA两个持久层框架哪个更好这样的结论。只是摆事实,讲道理,所以,请各位看官勿喷。 一、事件起因 关于Mybatis和JPA孰优孰劣的问题,争论已经很多年了。一直也没有结论,毕竟每个人的喜好和习惯是大不相同的。我也看...
项目中的if else太多了,该怎么重构?

程序员:我终于知道post和get的区别
IT界知名的程序员曾说:对于那些月薪三万以下,自称IT工程师的码农们,其实我们从来没有把他们归为我们IT工程师的队伍。他们虽然总是以IT工程师自居,但只是他们一厢情愿罢了。 此话一出,不知激起了多少(码农)程序员的愤怒,却又无可奈何,于是码农问程序员。 码农:你知道get和post请求到底有什么区别? 程序员:你看这篇就知道了。 码农:你月薪三万了? 程序员:嗯。 码农:你是怎么做到的? 程序员:
