spring boot 项目添加Jeresy框架的详细过程，希望对大家能有所帮助。 |
|
Jeresy是一个轻量级的JAX-RS框架
添加Jeresy 2.x的依赖
compile group:
'org.glassfish.jersey.core', name: 'jersey-client',
version: '2.26'
compile group: 'org.glassfish.jersey.containers',
name: 'jersey-container-servlet', version: '2.26'
compile group: 'org.glassfish.jersey.media', name:
'jersey-media-json-jackson', version: '2.26' |
build.gradle文件内容:
buildscript
{
ext {
springBootVersion = '1.5.8.RELEASE'
}
repositories {
mavenLocal()
maven{ url "http://SVN:8081/nexus/content/groups/public"}
mavenCentral()
jcenter()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
[compileJava, compileTestJava]*.options*.encoding
= 'UTF-8'
repositories {
mavenLocal()
maven{ url "http://SVN:8081/nexus/content/groups/public"}
mavenCentral()
jcenter()
}
dependencies {
compile('org.springframework.boot:spring-boot-configuration-processor')
compile('org.springframework.boot:spring-boot-starter-web')
compile group: 'org.glassfish.jersey.core',
name: 'jersey-client', version: '2.26'
compile group: 'org.glassfish.jersey.containers',
name: 'jersey-container-servlet', version: '2.26'
compile group: 'org.glassfish.jersey.media',
name: 'jersey-media-json-jackson', version:
'2.26'
testCompile('org.springframework.boot:spring-boot-starter-test')
} |
创建一个 spring boot 项目
在IDE里一路next
Spring Boot启动APP
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure
.SpringBootApplication;
@SpringBootApplication // @wjw 是Sprnig Boot项目的核心注解,主要目的是开启自动配置.
public class JerseyApplication {
public static void main(String[] args) {
SpringApplication.run(JerseyApplication.class,
args);
}
}
|
注册jersey servlet
这和原来在 web.xml 配置的是一样的,设置 Mapping,设置 init 初始化参数,对应的
servlet class name .
所有的rest/*请求都将被 ServletContainer jersey
servlet 容器接管.
package com.example.demo;
import org.glassfish.jersey.servlet.ServletContainer;
import org.glassfish.jersey.servlet.ServletProperties;
import org.springframework.boot.web.servlet.
ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.
Configuration;
@Configuration
public class ConfigBean {
@Bean
public ServletRegistrationBean jerseyServlet()
{
//手动注册servlet
ServletRegistrationBean registrationBean = new
ServletRegistrationBean(new ServletContainer(),
"/rest/*");
registrationBean.addInitParameter
(ServletProperties.JAXRS_APPLICATION_CLASS
,JerseyResourceConfig.class.getName());
return registrationBean;
}
} |
创建jersey Resources
packages方式是采用扫描包的方式批量注册
register 是单个注册
package com.example.demo;
import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.web.filter
.RequestContextFilter;
public class JerseyResourceConfig extends ResourceConfig
{
public JerseyResourceConfig() {
/*
* Servlet Filter that exposes the request to
the current thread, through both org.springframework.context.i18n.LocaleContextHolder
and RequestContextHolder. To be registered as
filter in web.xml.<br/>
Alternatively, Spring's org.springframework.web.context
.request.RequestContextListener
and Spring's org.springframework.web.servlet.DispatcherServlet
also expose the same request context to the
current thread.<br/>
This filter is mainly for use with third-party
servlets, e.g. the JSF FacesServlet. Within
Spring's own web support, DispatcherServlet's
processing is perfectly sufficient.<br/>
*/
register(RequestContextFilter.class);
// 加载资源文件,这里直接扫描com.example.
demo.controller下的所有api
packages("com.example.demo.controller");
//register(HelloController.class);
//@wjw_note:
这种是注册单个的 JAX-RS component!
}
} |
创建jersey Controller,使用 JAX-RS 规范的注解进行设置即可
package com.example.demo.controller;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import com.example.demo.User;
@Path("/user/")
public class HelloController {
@Path("{id}")
@GET
@Produces(MediaType.APPLICATION_JSON)
public User hello(@PathParam("id")
Long id) {
User user = new User();
user.setID(id);
user.setUserName("mvc.");
return user;
}
} |
启动Spring Boot程序
默认端口号是:8080
在浏览器里测试
输入:http://127.0.0.1:8080/rest//user/123678
返回: {"userName": "mvc.","id":
123678} |
