该问题是怎么引起的？(最新版上已修复的会直接close掉)

CourtUnit courtUnit = courtUnitService.getOne(Wrappers.lambdaQuery(new CourtUnit()).eq(CourtUnit::getCourtCode, courtRoom.getCourtCode()));

重现步骤

CourtUnit.isValidityFlag 该方法你看看是不是数据库命名 is_... 字段？ 建议修改命名方式不要 is 开头容易和 java 的 isXxx 混淆框架层读取错误

CourtUnit courtUnit = new CourtUnit(); courtUnit.setCourtCode(courtCode); CourtUnit result = courtUnitService.getOne(Wrappers.lambdaQuery(courtUnit)); 这种方式正常； CourtUnit courtUnit = courtUnitService.getOne(Wrappers.lambdaQuery(new CourtUnit()).eq(CourtUnit::getCourtCode, courtRoom.getCourtCode())); 这种方式报错； @TableField("sfyx") private Boolean validityFlag; public Boolean getValidityFlag() { return validityFlag; }

public void setValidityFlag(Boolean validityFlag) {
    this.validityFlag = validityFlag;
}

class ReflectionKit /* * 猜测方法名 * * @param field 字段 * @param str 属性字符串内容 / private static String guessGetterName(Field field, final String str) { return StringUtils.guessGetterName(str, field.getType()); }

3.2.0 无此StringUtils.guessGetterName方法 3.3.0有此方法

Comment From: IceFoxs

public static String getMethodCapitalize(Field field, final String str) { Class<?> fieldType = field.getType(); // fix #176 return StringUtils.concatCapitalize(boolean.class.equals(fieldType) ? "is" : "get", str); } issue 176
