Springboot是如此的暴力
在控制器中注解为@RestController类、@GetMapping或其他绘图注解方法后
会自动转成数据格式…

原因
因为@RestController是组合注解
等于SpringMVC：@Controller+@ResponstBody
package org.springframework.web.bind.annotation;import java.lang.annotation.Documented;import java.lang.annotation.ElementType;import java.lang.annotation.Retention;import java.lang.annotation.RetentionPolicy;import java.lang.annotation.Target;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.ResponseBody;@Target({ElementType.TYPE})@Retention(RetentionPolicy.RUNTIME)@Documented@Controller@ResponseBodypublic @interface RestController { String value() default "
Springboot自动转json的出现问题
问题复现
上代码：
1、实体类
package com.example.demo; /** * @author Mr.xiong * #description model * #date: 2022/4/8 10:08 * @version v1.0.0 * @since jdk8 */public class model { private String a; private String b; private boolean e; private Boolean f; public Boolean getF() { return false; } public boolean isE() { return false; } public boolean areC(){ return false; } public Boolean isD(){ return null; } public String getA() { return a; } public void setA(String a) { this.a = a; } public String getB() { return b; } public void setB(String b) { this.b = b; }}2、controller类
package com.example.demo;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;import java.util.ArrayList;import java.util.List; /** * @author Mr.xiong * #description web * #date: 2022/4/8 10:08 * @version v1.0.0 * @since jdk8 */@RestControllerpublic class web { @GetMapping public R demo(){ model m1 = new model(); m1.setA("a1"); m1.setB("b1"); model m2 = new model(); m2.setA("a2"); m2.setB("b2"); List<model> models = new ArrayList<>(); models.add(m1); models.add(m2); return R.success(200,"success",models); }}3、统一返回风格消息类
package com.example.demo; import java.util.Objects; /** * @author Mr.xiong * #description R * #date: 2022/4/8 10:08 * @version v1.0.0 * @since jdk8 */public class R { private Integer code; private String msg; private Object obj; public R(Integer code, String msg) { this.code = code; this.msg = msg; } public R(Integer code, String msg, Object obj) { this.code = code; this.msg = msg; this.obj = obj; } public Integer getCode() { return code; } public void setCode(Integer code) { this.code = code; } public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; } public Object getObj() { return obj; } public void setObj(Object obj) { this.obj = obj; } @Override public String toString() { return "R{" + "code=" + code + ", msg=" + msg + + ", obj=" + obj + }; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null getClass() != o.getClass()) return false; R r = (R) o; return code.equals(r.code) && msg.equals(r.msg) && obj.equals(r.obj); } @Override public int hashCode() { return Objects.hash(code, msg, obj); } public static R success(Integer code,String msg){ return new R(code, msg); } public static R success(Integer code,String msg,Object obj){ return new R(code, msg,obj); }}访问接口获得的数据如下：
问题分析及解决办法
public Boolean isD(){ return null; }可以看到，我们有这个方法，但是没有D这个属性，但是却实实在在打印了这个值。原因是因为springboot自动转json把他当做了一个属性。这是为什么呢？是因为布尔值的getter事实上boolean的getter方法就是 isXxxx，因此出现此问题也就不奇怪了解决方法，不要使用isXxx就可以避免此类问题。当我把isD修改为D之后，就解决了。
如下：
