spring boot controller设置 @Transactional 不回滚的解决办法

@Transactional
@ApiOperation(value = "添加一个用户信息")
@RequestMapping(value = "/create", method = RequestMethod.POST)
public RESTful create() {
    return userService.insert(null, null);
}

public RESTful insert(User user, Role role) {
    try {
        Date date = new Date();

        user = new User();
        user.setName("tq2");
        user.setAge(26);
        user.setCreate_at(date);

        userMapper.insertUser(user);

        role = new Role();
        //role.setName("role1");
        role.setCreate_at(date);

        roleMapper.insert(role);

        return new RESTful(CodeEnum.成功.getCode(), CodeEnum.成功.getMsg());
    } catch (Exception ex) {
        return new RESTful(CodeEnum.系统异常.getCode(), CodeEnum.系统异常.getMsg());
    }
}

1、role表的 name 字段不可空，但并不执行回滚

 2 @ApiOperation(value = "添加一个用户信息")
@RequestMapping(value = "/create", method = RequestMethod.POST)
public RESTful create() {
    try {
        return userService.insert(null, null);
    } catch (Exception ex) {
        return new RESTful(CodeEnum.系统异常.getCode(), CodeEnum.系统异常.getMsg());
    }
}

@Transactional
public RESTful insert(User user, Role role) {
    try {
        Date date = new Date();

        user = new User();
        user.setName("tq2");
        user.setAge(26);
        user.setCreate_at(date);

        userMapper.insertUser(user);

        role = new Role();
        //role.setName("role1");
        role.setCreate_at(date);

        roleMapper.insert(role);

        return new RESTful(CodeEnum.成功.getCode(), CodeEnum.成功.getMsg());
    } catch (Exception ex) {
        throw new RuntimeException();
    }
}
