1、制作SpringMVC控制器,并通过PostMan测试接口功能
名称:@RestController
类型:类注解
位置:基于SpringMVC的RESTful开发控制器类定义上方
作用:设置当前控制器类为RESTful风格,等同于@Controller与@ResponseBody两个注解组合功能
范例:
@RestController public class BookController{ }
名称:@GetMapping @PostMapping @PutMapping @DeleteMapping
类型:方法注解
位置:基于SpringMVC的RESTful开发控制器方法定义上方
作用:设置当前控制器方法请求访问路径与请求合作,每种对应一个请求动作,例如@GetMapping对应Get请求
范例:
@GetMapping("/{id}") public String getById(@PathVariable Integer id){ System.out.println("book getById..." + id); return "{'module':'book getById'}"; }属性:value(默认):请求访问路径
简化开发前:
简化开发后:
- @RestController
- @RequestMapping("/books")
- public class BookController{
-
- @PostMapping
- public String save(@RequestBody Book book){
- System.out.println("book save..." + book);
- return "{'module':'book save'}";
- }
-
- @PutMapping
- public String update(@RequestBody Book book){
- System.out.println("book update..." + book);
- return "{'module':'book update'}";
- }
- }
- @RestController
- @RequestMapping("/books")
- public class BookController {
-
- @PostMapping
- public String save(@RequestBody Book book){
- System.out.println("book save ==> "+ book);
- return "{'module':'book save success'}";
- }
-
- @GetMapping
- public List<Book> getAll(){
- System.out.println("book getAll is running ...");
- List<Book> bookList = new ArrayList<Book>();
-
- Book book1 = new Book();
- book1.setType("计算机");
- book1.setName("SpringMVC入门教程");
- book1.setDescription("小试牛刀");
- bookList.add(book1);
-
- Book book2 = new Book();
- book2.setType("计算机");
- book2.setName("SpringMVC实战教程");
- book2.setDescription("一代宗师");
- bookList.add(book2);
-
- Book book3 = new Book();
- book3.setType("计算机丛书");
- book3.setName("SpringMVC实战教程进阶");
- book3.setDescription("一代宗师呕心创作");
- bookList.add(book3);
-
- //模拟数据
- return bookList;
- }
-
- }
- @Configuration
- public class SpringMvcSupport extends WebMvcConfigurationSupport {
- //设置静态资源访问过滤,当前类需要设置为配置类,并被扫描加载
- @Override
- protected void addResourceHandlers(ResourceHandlerRegistry registry) {
- //当访问/pages/????时候,从/pages目录下查找内容
- registry.addResourceHandler("/pages/**").addResourceLocations("/pages/");
- registry.addResourceHandler("/js/**").addResourceLocations("/js/");
- registry.addResourceHandler("/css/**").addResourceLocations("/css/");
- registry.addResourceHandler("/plugins/**").addResourceLocations("/plugins/");
- }
- }
- //添加
- saveBook () {
- axios.post("/books",this.formData).then((res)=>{
-
- });
- },
-
- //主页列表查询
- getAll() {
- axios.get("/books").then((res)=>{
- this.dataList = res.data;
- });
- },
执行结果:
主页列表查询:
