我想使用SpringBoot和@RestController 這裏REST API創建Angularjs Web客戶端是實體產品：
package com.agTest.entities;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class Product implements Serializable{
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long idProduct;
private String description;
private double prix;
public Product() {
super();
// TODO Auto-generated constructor stub
}
public Product(String description, double prix) {
super();
this.description = description;
this.prix = prix;
}
public Long getIdProduct() {
return idProduct;
}
public void setIdProduct(Long idProduct) {
this.idProduct = idProduct;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public double getPrix() {
return prix;
}
public void setPrix(double prix) {
this.prix = prix;
}
}
這裏是我的ProductRepository接口使用JpaRepository：
package com.agTest.Dao;
import org.springframework.data.jpa.repository.JpaRepository;
import com.agTest.entities.Product;
public interface ProductRepository extends JpaRepository<Product, Long>{
}
這裏是我的ProductMetier接口：
package com.agTest.services;
import java.util.List;
import com.agTest.entities.Product;
public interface ProductMetier {
public Product saveProduct(Product p);
public List<Product> getProducts();
}
這裏是我的ProductMetierImpl類：
package com.agTest.services;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.agTest.Dao.ProductRepository;
import com.agTest.entities.Product;
@Service
public class ProductMetierImpl implements ProductMetier{
@Autowired
private ProductRepository productRepository;
@Override
public Product saveProduct(Product p) {
productRepository.save(p);
return p;
}
@Override
public List<Product> getProducts() {
return productRepository.findAll();
}
}
這裏是我的@RestController類：
package com.agTest.RestServices;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.agTest.entities.Product;
import com.agTest.services.ProductMetier;
@RestController
public class ProductRestService {
@Autowired
private ProductMetier productMetier;
@RequestMapping(value="/products", method=RequestMethod.POST)
public Product saveProduct(@RequestBody Product p){
return productMetier.saveProduct(p);
}
@RequestMapping(value="/products", method=RequestMethod.GET)
public List<Product> getProducts(){
return productMetier.getProducts();
}
}
這裏是我的application.properties：
# Datasource settings:
spring.datasource.url = jdbc:mysql://localhost:3306/agence_test
spring.datasource.username = root
spring.datasource.password =
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.jpa.database = MYSQL
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
我過我的API與郵遞員並且一切都很順利，但是當我嘗試創建angularjs客戶端時，http Post方法返回一個異常：
這裏是我的angularjs控制器：
var app=angular.module("AVG",[]);
app.controller("AVGController",function($scope,$http){
$scope.products=[];
$scope.description=null;
$scope.prix=null;
$scope.getProducts= function(){
$http.get("/products")
.success(function(data){
$scope.products=data;
})
.error(function(data){
alert("error");
});
};
// headers :{'Content-Type':'application/json'}
$scope.saveMembre= function(){
$http({
method : 'POST',
url : "/products",
data : "description="+$scope.description+"prix="+$scope.prix,
headers :{'Content-Type':'application/json'}
})
.success(function(data){
alert("success");
})
.error(function(data){
alert("error");
});
};
});
這裏是我的index.html：
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<link rel="stylesheet" type="text/css" href=""bootstrap-3.3.6-dist/css/bootstrap.min.css""/>
<title>Agence Test</title>
</head>
<body ng-app="AVG" ng-controller="AVGController">
<h1>AVE.com</h1>
<!-- Sauvegarde des Membres -->
<div>
<form>
<label>Description</label>
<input type="text" ng-model="description"/>
<label>Prix</label>
<input type="text" ng-model="prix"/>
<button ng-click="saveMembre()"> SAVE </button>
</form>
</div>
<!-- Affichage des Membres -->
<div >
<button type="button" ng-click="getProducts()">Get Products</button>
<table>
<tr>
<th>ID</th> <th>DESCRIPTION</th> <th>PRIX</th>
</tr>
<tr ng-repeat="item in products">
<td>{{item.idProduct}}</td>
<td>{{item.description}}</td>
<td>{{item.prix}}</td>
</tr>
</table>
<!-- <ul>
<li ng-repeat="item in membres"> {{item.idMembre}}</li>
<li ng-repeat="item in membres"> {{item.nomMembre}}</li>
</ul> -->
</div>
<script type="text/javascript" src="angular/angular.min.js"></script>
<script type="text/javascript" src="js/app.js"></script>
</body>
</html>
這裏異常調用HTTP POST方法返回的時候：
Hibernate: select product0_.id_product as id_produ1_0_, product0_.description as descript2_0_, product0_.prix as prix3_0_ from product product0_
Hibernate: select product0_.id_product as id_produ1_0_, product0_.description as descript2_0_, product0_.prix as prix3_0_ from product product0_
Hibernate: select product0_.id_product as id_produ1_0_, product0_.description as descript2_0_, product0_.prix as prix3_0_ from product product0_
Hibernate: select product0_.id_product as id_produ1_0_, product0_.description as descript2_0_, product0_.prix as prix3_0_ from product product0_
Hibernate: select product0_.id_product as id_produ1_0_, product0_.description as descript2_0_, product0_.prix as prix3_0_ from product product0_

的HTTP獲得方法按預期工作
p在我的PEF中租用我需要的任何幫助，我花了很多時間在上面！
