小编Rob*_*rto的帖子

应用程序spring + jpa + envers(hibernate)envers需要在特殊表中保存实体的历史记录.

在我保存了几次实体之后,我希望在USER表中看到填充版本字段,在USER_AUT中看到填充版本字段.但实际的结果是user表中正确的值,但在版本colums添加REV_TYPE,REV列(在现场只是种台的所有行)和空.

我使用4.0.1.Final hibernate

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-envers</artifactId>
    <version>4.0.1.Final</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>4.0.1.Final</version>
</dependency>

但是,当我查看表时,Version字段中的所有值都为null

我的实体是

import lombok.*;
import org.hibernate.annotations.GenericGenerator;
import org.hibernate.envers.Audited;

import javax.persistence.*;

@Entity
@Audited
@Table(name = "User", uniqueConstraints = {
        @UniqueConstraint(columnNames = { "prKey"})})
@NoArgsConstructor(access = AccessLevel.PUBLIC)
@AllArgsConstructor
@Getter
@Setter
public class User {
    @Id
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "uuid2")
    @Column(name = "PR_KEY", unique = true)
    private String prKey;

    @Column(name = "name", length = 100, unique = false)
    private String …

如何HttpServletResponse为单元测试创建，我可以在其中编写输出流和标头（不是MockHttpServletResponse）？在 assert 块中，我希望将OutputStream标头与标准具进行比较httpServletResponse。

我用过Spring4，java8和EasyMocklib。

现在，我有这样的组件：

它的代码：

import React from "react";
import {withStyles} from "material-ui/styles";
import Settings from "material-ui-icons/Settings"; 
import Button from "material-ui/Button";

const styles = {
button: {
    color: "primary",
    height: 95,
    width: 95,
    disableRipple: "true",
    focusRipple: "true",
},
icon: {
    height: 35,
    width: 35,
    display: "block",
    float: "none",
},
text: {
    height: 35,
    width: 35,
    display: "block",
    float: "none",
    marginTop: 10,
},
};

/* eslint-disable react/prop-types */
const IconedLabel = ({classes}) => (
<section>
    <Button className={classes.iconButton} variant="raised" color="primary">
        <Settings className={classes.icon}/>
        <div className={classes.text}>Message</div>
    </Button> …

默认的Typography材质-ui在新行上移动下一个tag-element，当下一个fe在此行时，如何自定义此组件？

我使用这个组件。

spring 4.13 上有应用程序 所以，当尝试在 websphere 8.5.5.13 上部署 ear-file 时 - 有错误消息

[12/18/18 14:56:41:946 MSK] 00000086 AnnotationCon E CWMDF0002E：注释处理失败，错误如下：com.ibm.ws.metadata.annotations.AnnotationException：类的注释处理失败：META-INF/版本/9/javax/xml/bind/ModuleUtil.class

这是一个什么样的问题？这可能是应用程序和服务器库的安装错误或错误不兼容？

应用程序有入口点

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"spring"})
public class WebAppInitalizer implements WebApplicationInitializer {
    private static final String CONFIG_LOCATION = "spring.config";
    private static final String MAPPING_URL = "/*";

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        System.out.println(">>>>>>>>>>>>>>>>>>>>>>> ONSTARTUP <<<<<<<<<<<<<<<<<<<<<<<<");
        WebApplicationContext context = getContext();
        servletContext.addListener(new ContextLoaderListener(context));
        ServletRegistration.Dynamic dispatcher = servletContext.addServlet("DispatcherServlet", new DispatcherServlet(context));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping(MAPPING_URL);
        System.out.println(">>>>>>>>>>>>>>>>>>>>>>> ONSTARTUP END <<<<<<<<<<<<<<<<<<<<<<<<");
    }

    private AnnotationConfigWebApplicationContext getContext() {
        AnnotationConfigWebApplicationContext …

我尝试从React&Redux第204页的书中实现示例,但是,有一个奇怪的问题 - There is TypeError (0 , _ColorReducer.color) is not a function error in React code

我有2个减速器用于一种颜色和颜色数组:

import React from "react";
import * as C from "./Constants";
import { color } from "./ColorReducer";

export const colorsReducer = (state = [], action) => {
  switch (action.type) {
    case C.ADD_COLOR:
      return [...state, color({}, action)];
    case C.RATE_COLOR:
      return state.map(item => color(item, action));
    default:
      return state;
  }
};

和

import React from "react";
import * as c from "./Constants";

export const ?olor = (state …

我对 Spring Boot 进行了单元测试：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = Application.class)
public class CustomerControllerIT {
    private RestTemplate restTemplate = new RestTemplate();
    @Test
    public void findAllCustomers() throws Exception {
        ResponseEntity<List<Customer>> responseEntity = restTemplate.exchange(
                "http://localhost:8080/Customer", HttpMethod.GET, null,
                new ParameterizedTypeReference<List<Customer>>() {
                });
        List<Customer> list = responseEntity.getBody();
        Assert.assertEquals(list.size(), 0);
    }
}

• 如果我在启动的应用程序上启动测试 - 测试正常

• 如果我尝试仅启动 IT，则会出现连接被拒绝的错误

我application.properties的单启动是一样的。

用于测试并位于资源和测试资源中。

Application.class 是：

@ComponentScan({"mypackage"})
@EntityScan(basePackages = {"mypackage.model"})
@EnableJpaRepositories(basePackages = {"mypackage.persistence"})
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

我有UT，顺利通过

    @Test
    public void test() {
        String text1 = "2009-07-10T14:30:01.001Z";
        String text2 = "2009-07-10T14:30:01.001+03:00";
        DateTimeFormatter f = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZ");

        ZonedDateTime zonedDateTime1 = ZonedDateTime.parse(text1, f);
        ZonedDateTime zonedDateTime2 = ZonedDateTime.parse(text2, f);

        System.out.println(zonedDateTime1);
        System.out.println(zonedDateTime2);
    }

输出是

2009-07-10T14:30:01.001Z
2009-07-10T14:30:01.001+03:00

但是，当我尝试在 spring-controller 上使用这种模式时

    @GetMapping
    public ResponseEntity get( @RequestParam("start") @DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZ")
                                               ZonedDateTime start) {
        Dto result = service.get(start);
        return new ResponseEntity(result, getHeaders(), HttpStatus.OK);
    }

例如，仅当我传递 Z 而不是时区时，它才有效

2009-07-10T14:30:01.001Z

但是当尝试传递时区偏移时 - 出现错误消息

“无法将类型“java.lang.String”的值转换为所需类型“java.time.ZonedDateTime”；嵌套异常为 org.springframework.core.convert.ConversionFailedException：无法从类型 [java.lang.String] 转换输入 [@org.springframework.web.bind.annotation.RequestParam @org.springframework.format.annotation.DateTimeFormat java.time.ZonedDateTime] 获取值 '2009-07-10T14:30:01.001 03:00'；嵌套异常是 java.lang.IllegalArgumentException：解析尝试失败的值 [2009-07-10T14:30:01.001 03:00]”，

我尝试像这样通过邮递员传递请求

我有两个组件Star和StarRating（（尝试实现来自React和Redux的书中的示例，第135页）。因此，我想渲染任何星星并在单击一颗星星时执行一些操作。因此，我尝试添加console.logonClick，但是没有用。您能帮我修复代码并解释为什么它不起作用吗？

StarRating.js

import React from "react";
import Star from "./Star";
import { Component } from "react";

class StarRating extends Component {
  displayName: "star-rating";

  constructor(props) {
    super(props);
    this.state = {
      totalStars: 5,
      starsSelected: 2
    };
    this.change = this.change.bind(this);
  }

  change(starsSelected) {
    console.log(starsSelected);
    this.setState({ starsSelected });
  }

  render() {
    const  totalStars  = 5;
    const { starsSelected } = this.state;
    console.log({ totalStars });
    return (
      <div className="star-rating">
        {[...Array(totalStars)].map((n, i) => {
          return (
            <Star
              key={i} …

spring+jpa(repositories) 实体有应用：

@Entity
@Getter
@Setter
@NoArgsConstructor
public class User{
  private int id;
  private String name;
  private String surname;
  private int age;
}

因此，我的存储库如下所示：

@Repository
public interface UserRepository extends CrudRepository<User, Integer>{
  public List<User> findUsersByNameAndAge(String name, int age);
  public List<User> findUsersByNameAndSurname(String name, String surname);
}

在我真正的生产代码中，参数太多，所以这个方法名太长而且不舒服。有没有办法从长方法名称中创建舒适的选项，例如仅查找？
