如何将 Spring REST API 添加到使用 spring xml 的现有应用程序
How to add a Spring REST API to an existing app that uses spring xml
我有一个现有的 Spring 应用程序,它是一个 Web 应用程序,我正在尝试向其添加 REST API。
我不确定如何连接一切才能正常工作
我已将条目添加到 web.xml。最初 servlet class 指向我创建的 DispatcherServlet,但我将它指向 org.springframework.web.servlet.DispatcherServlet 基于我在网上找到的东西。
web.xml
<servlet>
<servlet-name>rest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>

Class:
package com.company.platform.rest;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/rest")
public class RestDispatcherServlet {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
@GetMapping("/service/greeting")
public GreetingTest greeting(@RequestParam(value = "name", defaultValue = "World") String name) {
return new GreetingTest(counter.incrementAndGet(), String.format(template, name));
}
}
如能为我指明正确的方向,我们将不胜感激

答案是有一个过滤器处于活动状态,因此需要像这样向其中添加 /rest/ 入口点:
<filter>
<filter-name>SomeFilter</filter-name>
<filter-class>com.SomeFilter</filter-class>
<init-param>
<param-name>entryPoints</param-name>
<param-value>/someform.form,
/somejavascript.js
/rest/*
</param-value>
</init-param>
</filter>
